NullReferenceException in RewritePath()

[SoumyaSpirit]

Hi Guys... I use the RewritePath method to rewrite the internal path within the context.BeginRequest event. It’s working fine in my local System, but throwing System.NullReferenceException in the server.

So what could cause this error?

here is my code

 
using System;
using System.Collections.Generic;
using System.Web;
 
public class Redirect : IHttpModule
{
    public Redirect() { }
 
 
 
    public void Dispose()
    {
 
    }
 
    public void Init(HttpApplication context)
    {
        context.BeginRequest += new EventHandler(context_BeginRequest);
 
    }
 
 
    void context_BeginRequest(object sender, EventArgs e)
    {
        HttpApplication AppObject = (HttpApplication)sender;
        {
            string serverName = HttpUtility.UrlEncode(AppObject.Request.ServerVariables["SERVER_NAME"]);
            string filePath = AppObject.Request.FilePath;
            string queryurl = AppObject.Request.Url.Query;
            string absURL = AppObject.Request.Url.AbsoluteUri;
 
///Some condition
 
            string NewURLa = "/Default.aspx?TabId=189&NewsId=32453";
            HttpContext.Current.RewritePath(NewURLa);
        }
    }
}
 
 

here is Exception

System.Web.HttpUnhandledException: Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.NullReferenceException: Object reference not set to an instance of an object.
