Hi all,

I have created a web application with URL Rewriting. It's working absolutely fine on localhost. But when uploaded to production Server it stopped working.

Then I read some where that extentionless URLs are not suppoeted in IIS6 (or IIS configuration needs to be changed, and for that I have no control). Therefore I put .aspx extention. And it start working (both locally & on Production server). But now on Production server CSS & JavaScript Files are not loading but on localhost its working correctly.

I am using Global.asax & my own module for URL Rewriting.

Code on Global.asax file:

void Application_AcquireRequestState(object sender, EventArgs e)
{
    //Session is Available here
    string strLastURL = "";
    string fullOrigionalpath = HttpContext.Current.Request.Url.ToString().ToLower();

    if (fullOrigionalpath.Contains(".aspx")  && !fullOrigionalpath.Contains("404error.aspx"))
    {//Only .aspx files to be processed

        if (HttpContext.Current != null && HttpContext.Current.Session != null)
        {
            if (HttpContext.Current.Session["LastAccessURL"] != null)
                strLastURL = HttpContext.Current.Session["LastAccessURL"].ToString();
            else
                HttpContext.Current.Session["LastAccessURL"] = strLastURL = fullOrigionalpath;
        }

        if (fullOrigionalpath.Contains("/example.aspx") && fullOrigionalpath != strLastURL)
        {
            HttpContext.Current.Session["LastAccessURL"] = fullOrigionalpath;
            HttpContext.Current.Response.Redirect("~/ChangedByUrl/Example.aspx");
        }

        try
        {
            HttpContext.Current.Session["LastAccessURL"] = fullOrigionalpath;
        }
        catch { }
    }
}

Rewrite Module Code:

using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;

public class RewriteURL : IHttpModule
{
    public RewriteURL()
    {
        //
        // TODO: Add constructor logic here
        //
    }

    public void Init(HttpApplication application)
    {
        application.BeginRequest += (new EventHandler(this.Application_BeginRequest));
    }

    public void Dispose()
    {
    }

    private void Application_Disposed(Object source, EventArgs e)
    {

    }

    void Application_BeginRequest(object sender, EventArgs e)
    {
        string fullOrigionalpath = HttpContext.Current.Request.Url.ToString().ToLower();

        if (fullOrigionalpath.EndsWith("/changedbyurl/example.aspx"))
        {
            HttpContext.Current.RewritePath("~/Example.aspx");
        }
        else if (fullOrigionalpath.Contains("/changedbyurl/"))
        {
            //This is to correctly load the CSS & Java scrit files or Images etc on page.
            if (fullOrigionalpath.Contains("/changedbyurl"))
            {
                int start = 0;
                int end = 0;
                start = fullOrigionalpath.IndexOf("/changedbyurl");
                end = start + "/changedbyurl".Length;
                string strSubString = fullOrigionalpath.Substring(0, start);
                strSubString += "~" + fullOrigionalpath.Substring(end);
                fullOrigionalpath = strSubString;
            }

            string[] arr = fullOrigionalpath.Split('~');
            if (arr.Length > 1)
            {
                HttpContext.Current.RewritePath("~/" + arr[arr.Length - 1]);
            }
        }

    }
}

This working absolutely perfectly on local host but on production (having IIS6) CSS & JavaScript files are not loading.

On Master page inside head tag:

<link rel="stylesheet" href="jquery.megamenu.css" type="text/css" media="screen" />
    <link href="style.css" rel="stylesheet" type="text/css" />
    <link href="popup-div.css" rel="stylesheet" type="text/css" />
    <link href="style1.css" rel="stylesheet" type="text/css" />

The above CSS & Javascript files are loading correctly on Local host but not on production server. I do not want to manually fix the paths for them as absolute path. I wonder why this is happening?

To solve the CSS & Javascript files issue following approach is used by me:

protected void Page_Init(object sender, EventArgs e)
    {
        if (ViewState["OnceCalled"] != null)
            return;
        ViewState["OnceCalled"] = "Yes";
        objUtility.SetCssVersion(Page);
    }
    private void SetCssVersion(Control objHead)
    {
        foreach (Control c in EnumerateControlsRecursive(objHead))
        {
            if (c is HtmlLink)
            {
                HtmlLink lnkStylesheet = (HtmlLink)c;
                if (lnkStylesheet != null)
                {
                    if (lnkStylesheet.Href.Contains("?"))
                        lnkStylesheet.Href += "&" + Version();
                    else
                        lnkStylesheet.Href += "?" + Version();

                    if (!lnkStylesheet.Href.ToLower().Contains(".com") || !lnkStylesheet.Href.ToLower().Contains("http:"))
                    {
                        lnkStylesheet.Href = "Website name here/" + lnkStylesheet.Href;
                    }
                }
            }
        }
    }

But still Images are not loading.
I don't think this approach is good to make all image's URL absolute on page.

Or there's any other approach to handle this issue??

Any ideas??
