URL rewriting issue when postbacks and URL rewriting

When postback, it will cause a 301 redirect to get the rewrite page, so it will lose the original post.

The key solution:

protected void Page_Load(object sender, EventArgs e)
{
    if ( !String.IsNullOrEmpty(Request.ServerVariables["HTTP_X_ORIGINAL_URL"]) )
    {
        form1.Action = Request.ServerVariables["HTTP_X_ORIGINAL_URL"];
    }
}
