Redirect to an action from Application_BeginRequest in global.asax

Question

In my web application I am validating the url from glabal.asax . I want to validate the url and need to redirect to an action if needed. I am using Application_BeginRequest to catch the request event.

  protected void Application_BeginRequest(object sender, EventArgs e)
    {
        // If the product is not registered then
        // redirect the user to product registraion page.
        if (Application[ApplicationVarInfo.ProductNotRegistered] != null)
        {
             //HOW TO REDIRECT TO ACTION (action=register,controller=product)
         }
     }

Or is there any other way to validate each url while getting requests in mvc and redirect to an action if needed

Answer 1

All above will not work you will be in the loop of executing the method Application_BeginRequest.

You need to use

HttpContext.Current.RewritePath("Home/About"); 

Answer 2

Use the below code for redirection

   Response.RedirectToRoute("Default");

"Default" is route name. If you want to redirect to any action,just create a route and use that route name .

Answer 3

Besides the ways mentioned already. Another way is using URLHelper which I used in a scenario once error happend and User should be redirected to the Login page :

public void Application_PostAuthenticateRequest(object sender, EventArgs e){
    try{
         if(!Request.IsAuthenticated){
            throw  new InvalidCredentialException("The user is not authenticated.");
        }
    } catch(InvalidCredentialException e){
        var urlHelper = new UrlHelper(HttpContext.Current.Request.RequestContext);
        Response.Redirect(urlHelper.Action("Login", "Account"));
    }
}
