I am facing some problem when I call begin_request of httpModule. This begin_request is working/calling locally but when I upload it on production server than it is not calling . Please let me know the solution. Its very urgent for me.

My code is ---

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;

/// <summary>
/// Summary description for RewriteModule
/// </summary>
public class RewriteModule : IHttpModule
{

public void Init(HttpApplication context)
{
// it is necessary to
context.BeginRequest += new EventHandler(
RewriteModule_BeginRequest);


}
void RewriteModule_BeginRequest(object sender, EventArgs e)
{

string rawurl = HttpContext.Current.Request.Url.ToString();
string[] arr = rawurl.Split('/');
for (int i = 0; i < arr.Length; i++)
{
if (arr == "Pages")
{
i++;
if (arr == "default.aspx")
{
HttpContext.Current.Response.Redirect("../default.aspx");
break;
}
if (arr == "Admin.aspx")
{
HttpContext.Current.Response.Redirect("../Admin.aspx", false);
break;
}
if (arr == "UserAccount.aspx")
{
HttpContext.Current.Response.Redirect("../UserAccount.aspx", false);
break;
}
if (arr == "NewSearch.aspx")
{
HttpContext.Current.Response.Redirect("../NewSearch.aspx", false);
break;
}
if (arr == "NewAddHike.aspx")
{
HttpContext.Current.Response.Redirect("../NewAddHike.aspx", false);
break;
}
if (arr == "SafetyInfo.aspx")
{
HttpContext.Current.Response.Redirect("../SafetyInfo.aspx", false);
break;
}
if (arr == "Contact.aspx")
{
HttpContext.Current.Response.Redirect("../Contact.aspx", false);
break;
}

//else
//{
// HttpContext.Current.Response.Redirect(rawurl);
// break;
//}

}
}

}


public RewriteModule()
{

//TODO: Add constructor logic here

}
public void Dispose() { }
}


and I wrote some line in Web.config file

<httpModules>

<add name="RewriteModule" type="RewriteModule"/>

</httpModules>

Can you give us a copy on what you wrote on the web.config file for the URL Rewrite rule?
