• Thanks
  

• damn thats a lot of events.
  

• Any chance you could post the code on here. I would be interested to see how you implemeted this.
  

• What about LoadPostData and LoadViewState
  

• Do you know why the SaveViewState events fires twice for page and control?
  
  Page: SaveViewState
  Control: SaveViewState
  Page: SaveViewState
  Control: SaveViewState
  
  

• Thanks for the article.
  

• It seems you've been looking at some kind of Beta release. There are no such events as PreAuthenticateRequest, PreAuthorizeRequest, PreResolveRequestCache, PreAcquireRequestState, PreAcquireRequestState, PreReleaseRequestState and PreUpdateRequestCache in the ASP.NET 2.0 HttpApplication class (referred to you as the "Application"), not even private or internal ones. Decompile the System.Web.dll with the Reflector, if you like. Besides, you've missed the HttpSessionState.Start (Session_Start) and HttpSessionState.End (Session_End) events. Start occures just before AcquireRequestState and End occurs some configurable interval after the last request. Otherwise, this is an excellent list, it seems it will help me big with the page/control lifecycles.
  

• Of course it's based on pre-release... the post is more than two years old! Look at the date before you start lecturing.
  

• Hi Jeff
  
  The date published is a bit hidden in the GUI of the post. Usually in news publishing the date of the article is shown in other sytle(color) underneath the article title. In case of your blog the datestamp of your entry is mentioned underneath the body text. I had to look for a while (after reading your comment "Of course it's based on pre-release... ") to find the date.
  
  But anyhow. Thanks for writing down a list of events :)
