Thisarticle describes a complete solution for URL rewriting in ASP.NET 2.0.The solution uses regular expressions to specify rewriting rules andresolves possible difficulties with postback from pages accessed viavirtual URLs.

Why use URL rewriting?

The two main reasons to incorporate URL rewriting capabilities into your ASP.NET applications are usability and maintainability.

Usability

It is well-known that users of web applications prefer short, neatURLs to monstrous addresses packed with difficult to comprehend querystring parameters. From time to time, being able to remember and typein a concise URL is less time-consuming than adding the page to abrowser's favorites only to access later. Again, when access to abrowser's favorites is unavailable, it can be more convenient to typein the URL of a page on the browser address bar, without having toremember a few keywords and type them into a search engine in order tofind the page.

Compare the following two addresses and decide which one you like more:

(1)

http://www.somebloghost.com/Blogs/Posts.aspx?Year=2006&Month=12&Day=10

(2)

http://www. somebloghost.com/Blogs/2006/12/10/

The first URL contains query string parameters to encode the datefor which some blog engines should show available postings. The secondURL contains this information in the address, giving the user a clearidea of what he or she is going to see. The second address also allowsthe user to hack the URL to see all postings available in December,simply by removing the text encoding the day '10':http://www.somehost.com/Blogs/2006/12/.

Maintainability

In large web applications, it is common for developers to move pagesfrom one directory to another. Let us suppose that support informationwas initially available at http://www.somebloghost.com/Info/Copyright.aspx and http://www.somebloghost.com/Support/Contacts.aspx, but at a later date the developers moved the Copyright.aspx and Contacts.aspx pages to a new folder called Help.Users who have bookmarked the old URLs need to be redirected to the newlocation. This issue can be resolved by adding simple dummy pagescontaining calls to Response.Redirect(new location).However, what if there are hundreds of moved pages all over theapplication directory? The web project will soon contain too manyuseless pages that have the sole purpose of redirecting users to a newlocation.

Enter URL rewriting, which allows a developer to move pages betweenvirtual directories just by editing a configuration file. In this way,the developer can separate the physical structure of the website fromthe logical structure available to users via URLs.

Native URL mapping in ASP.NET 2.0

ASP.NET 2.0 provides an out-of-the-box solution for mapping staticURLs within a web application. It is possible to map old URLs to newones in web.config without writing any lines of code. To use URLmapping, just create a new urlMappings section within the system.web section of your web.config file and add the required mappings (the path ~/ points to the root directory of the web application):

<urlMappings enabled="true">
   <add url="~/Info/Copyright.aspx" mappedUrl="~/Help/Copyright.aspx" />
   <add url="~/Support/Contacts.aspx" mappedUrl="~/Help/Contacts.aspx" />
</urlMappings>

Thus, if a user types http://www.somebloghost.com/Support/Contacts.aspx, he can then see the page located at http://www.somebloghost.com/Help/Contacts.aspx, without even knowing the page had been moved.

This solution is fine if you have only two pages that have beenmoved to other locations, but it is completely unsuitable where thereare dozens of re-located pages, or where a really neat URL needs to becreated.

Another possible disadvantage of the native URL mapping technique is that if the page Contacts.aspx contains elements initiating postback to the server (which is most probable), then the user will be surprised that the URL http://www.somebloghost.com/Support/Contacts.aspx changes to http://www.somebloghost.com/Help/Contacts.aspx. This happens because the ASP.NET engine fills the action attribute of the form HTML tag with the actual path to a page. So the form renders like this:

<form name="formTest" method="post"
 action="http://www.simple-talk.com/Help/Contacts.aspx" id="formTest">
</form>

Thus, URL mapping available in ASP.NET 2.0 is almost always useless.It would be much better to be able to specify a set of similar URLs inone mapping rule. The best solution is to use Regular Expressions (foroverview see Wikipedia and for implementation in .NET see MSDN),but an ASP.NET 2.0 mapping does not support regular expressions. Wetherefore need to develop a different solution to built-in URL mapping.

The URL rewriting module

The best way to implement a URL rewriting solution is to createreusable and easily configurable modules, so the obvious decision is tocreate an HTTP Module (for details on HTTP Modules see MSDN Magazine)and implement it as an individual assembly. To make this assembly aseasy to use as possible, we need to implement the ability to configurethe rewrite engine and specify rules in a web.config file.

During the development process we need to be able to turn therewriting module on or off (for example if you have a bug that isdifficult to catch, and which may have been caused by incorrectrewriting rules). There should, therefore, be an option in therewriting module configuration section in web.config to turn the module on or off. So, a sample configuration section within web.config can go like this:

<rewriteModule>
  <rewriteOn>true</rewriteOn>
  <rewriteRules>
      <rule source="(/d+)/(/d+)/(/d+)/" 
         destination="Posts.aspx?Year=$1&amp;Month=$2&amp;Day=$3"/>
      <rule source="(.*)/Default.aspx" 
         destination="Default.aspx?Folder=$1"/>
  </rewriteRules>
</rewriteModule>

This means that all requests that run like: http://localhost/Web/2006/12/10/ should be internally redirected to the page Posts.aspx with query string parameters.

Please note that web.config is a well-formed XML file, and it is prohibited to use the symbol & in attribute value strings. In this case, you should use & instead in the destination attribute of the rule element.

To use the rewriteModule section in the web.config file, you need to register a section name and a section handler for this section. To do this, add a configSections section to web.config:

 <configSections>    <sectionGroup name="modulesSection">
      <section name="rewriteModule" type="RewriteModule.
                      RewriteModuleSectionHandler, RewriteModule"/>
    </sectionGroup>
  </configSections>

This means you may use the following section below the configSections section:

<modulesSection>
    <rewriteModule>
      <rewriteOn>true</rewriteOn>
      <rewriteRules>
              <rule source="(/d+)/(/d+)/(/d+)/"
destination="Post.aspx?Year=$1&amp;Month=$2&amp;Day=$3"/>
              <rule source="(.*)/Default.aspx"
destination="Default.aspx?Folder=$1"/>
      </rewriteRules>
    </rewriteModule>
  </modulesSection>

Another thing we have to bear in mind during the development of therewriting module is that it should be possible to use 'virtual' URLswith query string parameters, as shown in the following: http://www.somebloghost.com/2006/12/10/?Sort=Desc&SortBy=Date.Thus we have to develop a solution that can detect parameters passedvia query string and also via virtual URL in our web application.

So, let’s start by building a new Class Library. We need to add a reference to the System.Webassembly, as we want this library to be used within an ASP.NETapplication and we also want to implement some web-specific functionsat the same time. If we want our module to be able to read web.config, we need to add a reference to the System.Configuration assembly.

Handling the configuration section

To be able to read the configuration settings specified in web.config, we have to create a class that implements the IConfigurationSectionHandler interface (see MSDN for details). This can be seen below:

using System;
using System.Collections.Generic;
using System.Text;
using System.Configuration;
using System.Web;
using System.Xml;
 
 
namespace RewriteModule
{
    public class RewriteModuleSectionHandler : IConfigurationSectionHandler
    {
 
        private XmlNode _XmlSection;
        private string _RewriteBase;
        private bool _RewriteOn;
 
        public XmlNode XmlSection
        {
            get { return _XmlSection; }
        }
 
        public string RewriteBase
        {
            get { return _RewriteBase; }
        }
 
        public bool RewriteOn
        {
            get { return _RewriteOn; }
        }
        public object Create(object parent, 
                            object configContext,
                            System.Xml.XmlNode section)
        {
            // set base path for rewriting module to
            // application root
            _RewriteBase = HttpContext.Current.Request.ApplicationPath + "/";
 
            // process configuration section 
            // from web.config
            try
            {
                _XmlSection = section;
                _RewriteOn = Convert.ToBoolean(
                            section.SelectSingleNode("rewriteOn").InnerText);
            }
            catch (Exception ex)
            {
                throw (new Exception("Error while processing RewriteModule
                                         configuration section.", ex));
            }
            return this;
        }
    }
}

The Class RewriteModuleSectionHandler will be initialized by calling the Create method with the rewriteModule section of web.config passed as XmlNode. The SelectSingleNode method of the XmlNode class is used to return values for module settings.

Using parameters from rewritten URL

When handling virtual URLS such as http://www. somebloghost.com/Blogs/gaidar/?Sort=Asc(that is, a virtual URL with query string parameters), it is importantthat you clearly distinguish parameters that were passed via a querystring from parameters that were passed as virtual directories. Usingthe rewriting rules specified below:

<rule source="(.*)/Default.aspx" destination="Default.aspx?Folder=$1"/>,

you can use the following URL:

http://www. somebloghost.com/gaidar/?Folder=Blogs

and the result will be the same as if you used this URL:

http://www. somebloghost.com/Blogs/gaidar/

To resolve this issue, we have to create some kind of wrapper for'virtual path parameters'. This could be a collection with a staticmethod to access the current parameters set:

using System;
using System.Collections.Generic;
using System.Text;
using System.Collections.Specialized;
using System.Web;
 
namespace RewriteModule
{
 
    public class RewriteContext
    {
        // returns actual RewriteContext instance for
        // current request
        public static RewriteContext Current
        {
            get
            {
                // Look for RewriteContext instance in
                // current HttpContext. If there is no RewriteContextInfo
                // item then this means that rewrite module is turned off
                if(HttpContext.Current.Items.Contains("RewriteContextInfo"))
                    return (RewriteContext)
                      HttpContext.Current.Items["RewriteContextInfo"];
                else
                    return new RewriteContext();
            }
        }
 
        public RewriteContext()
        {
            _Params = new NameValueCollection();
            _InitialUrl = String.Empty;
        }
 
        public RewriteContext(NameValueCollection param, string url)
        {
            _InitialUrl = url;
            _Params = new NameValueCollection(param);
            
        }
 
        private NameValueCollection _Params;
 
        public NameValueCollection Params
        {
            get { return _Params; }
            set { _Params = value; }
        }
 
        private string _InitialUrl;
 
        public string InitialUrl
        {
            get { return _InitialUrl; }
            set { _InitialUrl = value; }
        }
    }
}

You can see from the above that it is possible to access 'virtual path parameters' via the RewriteContext.Current collection and be sure that those parameters were specified in the URL as virtual directories or pages names, and not as query string parameters.

Rewriting URLs

Now let's try some rewriting. First, we need to read rewriting rules from the web.configfile. Secondly, we need to check the actual URL against the rules and,if necessary, do some rewriting so that the appropriate page isexecuted.

We create an HttpModule:

class RewriteModule : IHttpModule
{
public void Dispose() { }
public void Init(HttpApplication context)
{}
}

When adding the RewriteModule_BeginRequestmethod that will process the rules against the given URL, we need tocheck if the given URL has query string parameters and call HttpContext.Current.RewritePath to give control over to the appropriate ASP.NET page.

using System;
using System.Collections.Generic;
using System.Text;
using System.Web;
using System.Configuration;
using System.Xml;
using System.Text.RegularExpressions;
using System.Web.UI;
using System.IO;
using System.Collections.Specialized;
 
namespace RewriteModule
{
    class RewriteModule : IHttpModule
    {
 
        public void Dispose() { }
 
        public void Init(HttpApplication context)
        {
            // it is necessary to 
            context.BeginRequest += new EventHandler(
                 RewriteModule_BeginRequest);
        }
 
        void RewriteModule_BeginRequest(object sender, EventArgs e)
        {
 
            RewriteModuleSectionHandler cfg =
               (RewriteModuleSectionHandler)
                  ConfigurationManager.GetSection
                   ("modulesSection/rewriteModule");
 
            // module is turned off in web.config
            if (!cfg.RewriteOn) return; 
 
            string path = HttpContext.Current.Request.Path;
 
            // there us nothing to process
            if (path.Length == 0) return; 
 
            // load rewriting rules from web.config
            // and loop through rules collection until first match
            XmlNode rules = cfg.XmlSection.SelectSingleNode("rewriteRules");
            foreach (XmlNode xml in rules.SelectNodes("rule"))
            {
                try
                {
                    Regex re = new Regex(
                     cfg.RewriteBase + xml.Attributes["source"].InnerText,
                     RegexOptions.IgnoreCase);

                    Match match = re.Match(path);
                    if (match.Success)
                    {
                        path = re.Replace(
                             path, 
                             xml.Attributes["destination"].InnerText);

                        if (path.Length != 0)
                        {
                            // check for QueryString parameters
                       if(HttpContext.Current.Request.QueryString.Count != 0)
                       {
                       // if there are Query String papameters
                       // then append them to current path
                       string sign = (path.IndexOf('?') == -1) ? "?" : "&";
                       path = path + sign +
                          HttpContext.Current.Request.QueryString.ToString();
                       }
                       // new path to rewrite to
                       string rew = cfg.RewriteBase + path;
                       // save original path to HttpContext for further use
                       HttpContext.Current.Items.Add(
                         "OriginalUrl", 
                         HttpContext.Current.Request.RawUrl);
                       // rewrite
                       HttpContext.Current.RewritePath(rew);
                       }
                       return;
                    }
                }
                catch (Exception ex)
                {
                    throw (new Exception("Incorrect rule.", ex));
                }
            }
            return;
        }
 
    }
}

We must then register this method:

public void Init(HttpApplication context)
{
 context.BeginRequest += new EventHandler(RewriteModule_BeginRequest);
}

But this is just half of the road we need to go down, because therewriting module should handle a web form's postbacks and populate acollection of 'virtual path parameters'. In the given code you will notfind a part that does this task. Let's put 'virtual path parameters'aside for a moment. The main thing here is to handle postbackscorrectly.

If we run the code above and look through the HTML source of theASP.NET page for an action attribute of the form tag, we find that evena virtual URL action attribute contains a path to an actual ASP.NETpage. For example, if we are using the page ~/Posts.aspx to handle requests like http://www. somebloghost.com/Blogs/2006/12/10/Default.aspx, we find the action="/Posts.aspx". This means that the user will be using not the virtual URL on postback, but the actual one: http://www. somebloghost.com/Blog.aspx. This is not what we want to use here! So, a few more lines of code are required to achieve the desired result.

First, we must register and implement one more method in our HttpModule:

        public void Init(HttpApplication context)
        {
            // it is necessary to 
            context.BeginRequest += new EventHandler(
                 RewriteModule_BeginRequest);
            context.PreRequestHandlerExecute += new EventHandler(
                 RewriteModule_PreRequestHandlerExecute);
        }
 
      void RewriteModule_PreRequestHandlerExecute(object sender, EventArgs e)
        {
            HttpApplication app = (HttpApplication)sender;
            if ((app.Context.CurrentHandler is Page) && 
                 app.Context.CurrentHandler != null)
            {
                Page pg = (Page)app.Context.CurrentHandler;
                pg.PreInit += new EventHandler(Page_PreInit);
            }
        }

This method checks if the user requested a normal ASP.NET page and adds a handler for the PreInit event of the page lifecycle. This is where RewriteContextwill be populated with actual parameters and a second URL rewritingwill be performed. The second rewriting is necessary to make ASP.NETbelieve it wants to use a virtual path in the action attribute of anHTML form.

void Page_PreInit(object sender, EventArgs e)
        {
            // restore internal path to original
            // this is required to handle postbacks
            if (HttpContext.Current.Items.Contains("OriginalUrl"))
            {
              string path = (string)HttpContext.Current.Items["OriginalUrl"];
 
              // save query string parameters to context
              RewriteContext con = new RewriteContext(
                HttpContext.Current.Request.QueryString, path);
 
              HttpContext.Current.Items["RewriteContextInfo"] =  con;
 
              if (path.IndexOf("?") == -1)
                  path += "?";
              HttpContext.Current.RewritePath(path);
            }
        }

Finally, we see three classes in our RewriteModule assembly:

Registering RewriteModule in web.config

To use RewriteModule in a web application, you should add a reference to the rewrite module assembly and register HttpModule in the web application web.config file. To register HttpModule, open the web.config file and add the following code into the system.web section :

<httpModules>
<add name="RewriteModule" type="RewriteModule.RewriteModule, RewriteModule"/>
</httpModules>

Using RewriteModule

There are a few things you should bear in mind when using RewriteModule:

It is impossible to use special characters in a well-formed XML document which is web.config in its nature. You should therefore use HTML-encoded symbols instead. For example, use & instead of &.
To use relative paths in your ASPX pages, you should call the ResolveUrl method inside HTML tags: <img src="<%=ResolveUrl("~/Images/Test.jpg")%>" />. Note, that ~/ points to the root directory of a web application.
Bear in mind the greediness of regular expressions and put rewriting rules to web.config in order of their greediness, for instance:

<rule source="Directory/(.*)/(.*)/(.*)/(.*).aspx"
   destination="Directory/Item.aspx?
   Source=$1&amp;Year=$2&amp;ValidTill=$3&amp;Sales=$4"/>
<rule source="Directory/(.*)/(.*)/(.*).aspx"
   destination="Directory/Items.aspx?
   Source=$1&amp;Year=$2&amp;ValidTill=$3"/>
<rule source="Directory/(.*)/(.*).aspx"
   destination="Directory/SourceYear.aspx?
   Source=$1&amp;Year=$2&amp;"/>
<rule source="Directory/(.*).aspx"
   destination="Directory/Source.aspx?Source=$1"/>

If you would like to use RewriteModulewith pages other than .aspx, you should configure IIS to map requeststo pages with the desired extensions to ASP.NET runtime as described inthe next section.

IIS Configuration: using RewriteModule with extensions other than .aspx

To use a rewriting module with extensions other than .aspx (forexample, .html or .xml), you must configure IIS so that these fileextensions are mapped to the ASP.NET engine (ASP.NET ISAPI extension).Note that to do so, you have to be logged in as an Administrator.

Open the IIS Administration console and select a virtual directory website for which you want to configure mappings.

Windows XP (IIS 5)
Virtual Directory "RW"

Windows 2003 Server (IIS 6)
Default Web Site

Then click the Configuration… button on the Virtual Directory tab (or the Home Directory tab if you are configuring mappings for the website).

Windows XP (IIS 5)

Windows 2003 Server (IIS 6)

Next, click on the Add button andtype in an extension. You also need to specify a path to an ASP.NETISAPI Extension. Don't forget to uncheck the option Check that file exists.

If you would like to map all extensions to ASP.NET, then for IIS 5on Windows XP you have only to map .* extension to the ASP.NET ISAPIextension. But for IIS 6 on Windows 2003 you have to do it in aslightly different way: click on the Insert… button instead of the Add… button, and specify a path to the ASP.NET ISAPI extension.

Conclusions

Now we have built a simple but very powerful rewriting module forASP.NET that supports regular expressions-based URLs and pagepostbacks. This solution is easily implemented and gives users theability to use short, neat URLs free of bulky Query String parameters.To start using the module, you simply have to add a reference to the RewriteModule assembly in your web application and add a few lines of code to the web.configfile, whereupon you have all the power of regular expressions at yourdisposal to override URLs. The rewrite module is easily maintainable,because to change any 'virtual' URL you only need to edit the web.config file. If you need to test your application without the module, you can turn it off in web.config without modifying any code.

To gain a deeper insight into the rewriting module, take a lookthrough the source code and example attached to this article. I believeyou'll find using the rewriting module a far more pleasant experience,than using the native URL mapping in ASP.NET 2.0.

Subject: IIS6 404? Posted by: Anonymous (not signed in) Posted on: Monday, March 26, 2007 at 1:26 PM Message: Great article!

Ihave followed your setup etc. and no matter what I try, IIS6 (Win2k3server) returns a 404 when I try to access the URL that needs to bere-written. For example:

http://www.foo.com/Books/123 should be re-written as http://www.foo.com/Books.aspx?ID=123

butIIS always seems to return the generic 404 error page (“page ordirectory not found” – there is no “Books” directory on the web root).Any thoughts to what IIS setting might be causing this?

Thanks!

1. If you want to rewrite /Test/1.aspx to /Test.aspx?id=1 you should use the following rule:

<rule source="Test/(.*)Default.aspx" destination="/Test.aspx?id=$1"/>,

2.Question with IP address is not for my rewriting solution but forintegrated URL mapping functionality in ASP.NET. But I can answer - youhave to configure IIS web server to handle .* (all extensions) withASP.NET ISAPI filter to use extensionless URLs

3. As for 404 error - double check if you turn off Verify That File Exist option in IIS configuration for .* "extension"

Best,
Gaidar

Subject: There is a bug !! Please see here. Posted by: doggy8088 (view profile) Posted on: Sunday, May 06, 2007 at 2:24 PM Message: Your module will not execute smoothly when install website in root web application:

Line 36 of RewriteModuleSectionHandler.cs:

_RewriteBase = HttpContext.Current.Request.ApplicationPath + "/";

Should rewrite as

if (!HttpContext.Current.Request.ApplicationPath.EndsWith("/"))
{
_RewriteBase = HttpContext.Current.Request.ApplicationPath + "/";
}

That'sbecause when your web ap run in root url, theHttpContext.Current.Request.ApplicationPath will be "/", if you appendan "/" will cause file not found error.

Subject: Avoid .* and make sure you're not missing files Posted by: Anonymous (not signed in) Posted on: Thursday, May 10, 2007 at 1:16 AM Message: Mapping.* to aspnet_isapi means that every file on the web server is served upby ASP.NET. You're giving .NET processing duties that are normallyhandled by IIS. When a page loads, .NET isn't handling one page, it'shandling one page PLUS any number of .css, .js, .gif, .jpg, or .pngfiles. Multiply that by every page load of every user of every site onthe server, and .NET's performance starts to degrade.

Instead,you can set the custom 404 error in IIS to point to something like URL/404.aspx and handle the rewriting from there. That way, .NET onlyneeds to handle missing files, like "/MyVirtualPage/".

In eithercase, it's important to make sure you aren't missing any images orlinked files. If any file is missing, ASP.NET will return its 404 errorpage (or your custom 404 page), doing extra work for no reason.

Nowlet's take it a step further to witness the destructive potential of asingle missing image. Let's say you have a master page (or a controlused on all pages), and it has an image tag pointing to an image thatno longer exists. When it can't find the image, the Web.config tells.NET to load your custom 404 page. But your custom 404 page uses thesame master page with the same missing image, so now you've got aninfinite loop, dragging down the performance of the entire server.

Subject: Maintainability and Usability Posted by: Anonymous (not signed in) Posted on: Wednesday, May 16, 2007 at 10:56 AM Message: Agood article, although usability and maintainability are not goodreasons to consider rewrting your urls. A user experienced enough tomanipulate the flattened will be able to manipulate the dynamicversion. I also do not want users manipulating url's if i can help it.

Howeverrewriting your urls as meaningful textual phrases is a great idea, notjust for the user but more importantly for search engines!!!

Subject: Answers Posted by: Anonymous (not signed in) Posted on: Friday, May 18, 2007 at 7:47 AM Message:
Sorry that it took too long for me to get here and answer your questions - I do apologize but I'm really busy these days.

Firstof all, most of the problems arise because of relative paths, so it isbetter to use paths starting from the root. Thus, you should use thefollowing for an image:
<img src="<%=ResolveUrl("~/Images/MyImage.jpg")%>" />
or the following for CSS:
<link rel="stylesheet" href="<%=ResolveUrl("~/Css/MyCss.css")%>" type="text/css" />

Of course, you may use direct href tag if you are specifying url starting from the root, e.g.:
<a href="/MySite/Page/MyPage.aspx" />

This is a price you have to pay for URL rewriting...

The next "problem generator" is regular expression you are using...

For BramptonPages - could you please show me rewriting rules you are using?

Doubledslash (//) not raising issues actually because it is simple ignored...But your solution is good, I had to do that. Thanks!

As formapping .* to ASP.NET - I myself don't like the idea (maybe because I'mserved by ASP.NET I like to know it is ASP.NET from the URL and not.php or .pl :)).

As for Scott Mitchell's article. I have notseen it before because I have been using this type of rewriting formore than 3 years now and never Google/Live/Yahoo and etc. forrewriting solutions...

As for this rule:

<rule source="(/d+)/(/d+)/(/d+)/" destination="Default2.aspx?blogID=333"/>

Yourregular expression simply is wrong - it will do for something like/Rewrite.Test/10/20/30/. If you like to use a rule for/Rewrite.Test/blogs/Caroline/blogs.aspx then you have to use thefollowing rule:

<rule source="(/w+)/(/w+)/(/w+).aspx/" destination="Default2.aspx?blogID=333"/>

Thank you all for your comments!

Subject: Deployment Posted by: jabailo (view profile) Posted on: Tuesday, August 12, 2008 at 4:22 PM Message: How do I deploy this application to another machine?

Assuming that I do not compile this on the target machine:

Into what directory do I copy the .dll?

Do I add to the global assembly cache? Or run regsvr32?

How do I get to the point of being able to register the module in web.config?

Subject: Cannot Run as Website, only Virtual Directory Posted by: jabailo (view profile) Posted on: Wednesday, August 13, 2008 at 12:47 PM Message: Iwas able to publish the Release code to a virtual directory on a remoteserver. After setting the wildcard filter to aspnet_isapi.dll the samewebsite worked fine.

However, if I try to run it as it's own website, with its own IP address and do exactly the same thing, I get the 404 error!

Infact I made a virtual directory in the website, and pointed it to thesame code, then made the isapi change, and it worked as well!

But I cannot run it as the top level of the website.

Can you suggest why this might happen?

Subject: This solution is NOT recommended. Use urlrewriter.net Posted by: SandeepKumar (view profile) Posted on: Thursday, August 14, 2008 at 4:10 AM Message: This thing is not working in IIS 6 Win2K3 website.
Me and my team wasted lots of time using this, and found this UrlRewriter.NET.

UrlRewriter.NET is an open source solution which works with Win2K, Win2K3 and WinXP; and compatible with ASP.NET 1.1 and 2.

It has good regular expression support and lots of other features.

Please have a look, http://urlrewriter.net/index.php/support

ForASP.NET 3.5 check this article by scottguhttp://weblogs.asp.net/scottgu/archive/2007/02/26/tip-trick-url-rewriting-with-asp-net.aspx

Subject: Google indexing Posted by: denniswong288 (view profile) Posted on: Monday, October 20, 2008 at 7:55 PM Message: Hi,

I'm using urlrewriting.net for my site's URLRewriting.

Was wondering if Google indexes pages using urlrewriting.net? or is this all a hype?

The thing is I've seen numerous posts that Google does not index pages using "urlrewriter.net".
However, I've not seen any regarding "urlrewriting.net".

Please note that these are 2 separate UrlRewriting solutions from 2 different teams/companies.

Thanks!
