    Global.asax replacement in Umbraco 6

    I had the following in my Global.asax (Umbraco 4.7)

    • Application_Start
    • Application_EndRequest
    • Application_Error
    • Session_Start
    • Session_End

    Now I have upgraded to Umbraco 6.0.3, which global.asax inherits from Umbraco.Web.UmbracoApplication

    Where do I put my event handlers (and what are the equivalent method names for each)?

    Thanks in advance!

    You can find more info here: http://our.umbraco.org/Documentation/Reference/Events/application-startup

    You could also create a new Global.cs and let Umbraco inherit from that. Here is an example:

    Global.cs:

    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Web;
    
    namespace Umbraco.Extensions.Utilities
    {
        public class Global : Umbraco.Web.UmbracoApplication
        {
            public override string GetVaryByCustomString(HttpContext context, string custom)
            {
                if (custom.ToLower() == "url")
                {
                    return "url=" + context.Request.Url.AbsoluteUri;
                }
    
                return base.GetVaryByCustomString(context, custom);
            }
        }
    }

    Global.asax from Umbraco

    <%@ Application Codebehind="Global.asax.cs" Inherits="Umbraco.Extensions.Utilities.Global" Language="C#" %>

    Hi Jeroen, thank you for your quick reply.

    I have looked into IApplicationEventHandler (since I'm using Umbraco 6.0.3) and extending Umbraco.Web.UmbracoApplication.

    However my problem remains: Which one do I use and what methods can I use to replace:

    • Application_Start
    • Application_EndRequest
    • Application_Error
    • Session_Start
    • Session_End

    I couldn't find all 5 of them on either of those class, and implementing IApplicationEventHandler gives me this error:

    Values cannot be returned until Resolution is frozen

    If you want to replace those values (which you don't have too if you only want to use events) I think it's best to override the Global.asax like I did in my example.

    That's cool, except I only found EndRequest and Error, and this is my class now

    public class Global : Umbraco.Web.UmbracoApplication
    {
      public void Init(HttpApplication application)
      {
          application.EndRequest += (new EventHandler(this.Application_EndRequest));
          application.Error += new EventHandler(Application_Error);
      }
       
      private void Application_EndRequest(object sender, EventArgs e)
      {
          // My code
      }
       
      private void Application_Error(object sender, EventArgs e)
      {
          // My code
      }
    }

    Do you know what are the equivalent for:

    • Application_Start
    • Session_Start
    • Session_End

    Listening, as I've run into the exact same problem now.

    The document that Jeroen points to has examples on all v4.x of Umbraco, plus v6.1. Which is strange, since 6.1 looks like a future version. And it doesn't seem like it is a typo (fx. should have read 6.0.1) as, just as Hardi states, I can't find anything equivalent to Application_Start.

    I'm also still waiting for an answer.

    You can override OnApplicationStarted but I couldn't use it (Request is unavailable yet at that point)

      protected override void OnApplicationStarted(object sender, EventArgs e)
      {
      }

    The closest I could find so far is this

    application.PreRequestHandlerExecute += new EventHandler(application_PreRequestHandlerExecute);

    Looks like I've got the following working with v6.0.5:

    using Umbraco.Core;
    using Umbraco.Web;
    using umbraco.BusinessLogic; namespace MySite { public class EventHandlers : Umbraco.Core.IApplicationEventHandler { public void OnApplicationInitialized(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext) { } public void OnApplicationStarted(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext) { } public void OnApplicationStarting(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext) { Log.Add(LogTypes.Custom, -1, "BaZinga!"); } } }

    Somebody knows how to use Application_Error in the IApplicationEventHandler? Or how do i catch a http 400 error?

    Hi all, 

    I was using the URL rewriting in UMBRACO 4.7.2 on my custom Global.asax file into the Application_BeginRequest method. Now I'm trying to upgrade to version 6.0.0 where I saw that I have to change my custom Global.asax to inherit from Umbraco.Web.UmbracoApplication.

    No problems so far in general in the application, but when the global.asax triggers the HttpContext.Current.RewritePath(URL), after migrating to version 6, the method does not rewrite the URL at all. It does not give any error or exception, it simply doesn't rewrite the URL, and consequently the system returns 404 , file not found.

    Any ideas about it? Did the version 6 of Umbraco stop to support the HttpContext.Current.RewritePath method in its new Global.asax?

    Thanks in advance to all of you!
