.net 中URL 重写post提交后的地址变为了原地址
让Page类继承OLPage 类就可以了，如：

public partial class Bottom : gcy.Utility.OLPage
    {
        protected void Page_Load(object sender, EventArgs e)
        {

}
}

-----------------------------------------------------------------------
gcy.Utility namespace :

using System;
using System.IO;
using System.Web;
using System.Web.UI;
namespace gcy.Utility
{
    public class OLPage : Page
    {
        public OLPage()
        {

        }
        protected override void Render(HtmlTextWriter writer)
        {
            if (writer is System.Web.UI.Html32TextWriter)
            {
                writer = new FormFixerHtml32TextWriter(writer.InnerWriter);
            }
            else
            {
                writer = new FormFixerHtmlTextWriter(writer.InnerWriter);
            }
            base.Render(writer);
        }
    }

    internal class FormFixerHtml32TextWriter : System.Web.UI.Html32TextWriter
    {
        private string _url; // 假的URL
        internal FormFixerHtml32TextWriter(TextWriter writer):base(writer)
        {
            _url = HttpContext.Current.Request.RawUrl;
        }
        public override void WriteAttribute(string name,string value,bool encode)
        {
            if (_url != null && string.Compare(name,"action",true) == 0)
            {
            value = _url;
            }
            base.WriteAttribute(name,value,encode);
        }
    }
    internal class FormFixerHtmlTextWriter : System.Web.UI.HtmlTextWriter
    {
        private string _url;
        internal FormFixerHtmlTextWriter(TextWriter writer):base(writer)
        {
            _url = HttpContext.Current.Request.RawUrl;
        }
        public override void WriteAttribute(string name,string value,bool encode)
        {
            if (_url != null && string.Compare(name,"action",true) == 0)
            {
            value = _url;
            }
            base.WriteAttribute(name,value,encode);
        }
    }

}
