Give some Examples That we can do in each Application events like Application_AuthenticateRequest

void Application_BeginRequest(object sender, EventArgs e)
       {
           // Code that runs on application startup
           // Check whether to begin the request

       }
       void Application_AuthenticateRequest(object sender, EventArgs e)
       {

           /*This is called just before authentication is performed.
            * You could add your own authentication logic in this method to provide custom authentication*/

       }
       void Application_AuthorizeRequest(object sender, EventArgs e)
       {
           /*This is called when the authentication stage is completed.
            * It's executed at the stage to determine user privileges and permissions.
            * You could add custom code to assign user special privileges.*/

       }
       void Application_ResolveRequestCache(object sender, EventArgs e)
       {
           // Code that runs on application startup

       }
       void Application_AcquireRequestState(object sender, EventArgs e)
       {
           /*This is called just before session-specific data is retrieved for the client
            * and is used to populate Session Collection.*/
       }
       void Application_PreRequestHandlerExecute(object sender, EventArgs e)
       {
           // Code that runs on application startup

       }


       //Handler Now Execute the request



       void Application_PostRequestHandlerExecute(object sender, EventArgs e)
       {


       }
       void Application_ReleaseRequestState(object sender, EventArgs e)
       {
           /* This method is called when the session-specific information is about to be serialized
            * from the Session Collection so that it's available for the next request. */

       }
       void Application_UpdateRequestCache(object sender, EventArgs e)
       {
           //This is called just before information is added to the output cache.
           //If you have enabled output caching for your web page,
           //it's now the time ASP.NET insert the rendered HTML into the cache.


       }
