I have multiple nested update panels and i want to generate seperate sessionids for asynchronous postbacks and complete postbacks. I will be using the sessionid as a key for my custom caching object and the cached object will be reused in other pages. Also i want to generate a different sessionid when the application is opened in the second tab in the same browser. Since i have update panels in my pages, if i am able to differentiate asynchronous postbacks and complete postbacks i will be able to generate a different sessionid.

If you have any data that is page specific, you should not store it in session state, you should make it follow the page. Despite everything, the person most likely to be fooling you next is yourself.

There is no way to control this issue

I have no idea since my experience with AJAX is really limited. You should be asking this in the ASP.NET forum, not C#. A guide to posting questions on CodeProject[^] Dave Kreskowiak Microsoft MVP Visual Developer - Visual Basic      2006, 2007, 2008
