How to 301 redirect in ASP.NET 4.0?

Solution
Main problem: Your're doing the above stuff in `Application_Start` - which is only executed once. You should hook up with each request. Try this:
void Application_BeginRequest(object sender, EventArgs e)
{
// Code that runs on every request
if (HttpContext.Current.Request.Url.ToString().ToLower().Contains("http://website.net"))
{
HttpContext.Current.Response.Status = "301 Moved Permanently";
HttpContext.Current.Response.AddHeader("Location", Request.Url.ToString().ToLower().Replace("http://website.net", "http://www.website.net"));
}
}
An even better approach would be to use URL rewriting, which can be configured from within `Web.Config`:
Microsoft rewriting module - Force www on url Or remove www from url
Problem
I am trying to implement URL redirect for the website rather than doing it page by page. I want to do it in the global.asax file. Below is the code i have defined. I want to have http://website.net as my main url & want to have a permanent URL redirect if someone types in http://www.website.net. Unfortunately it is not working for the live website. Can anyone point out the problem in the code. The code doesn't generate any error. ``` void Application_Start(object sender, EventArgs e) { // Code that runs on application startup if (HttpContext.Current.Request.Url.ToString().ToLower().Contains("http://website.net")) { HttpContext.Current.Response.Status = "301 Moved Permanently"; HttpContext.Current.Response.AddHeader("Location", Request.Url.ToString().ToLower().Replace("http://website.net", "http://www.website.net")); } } ```
