Session Variables not saved when page is in an iFrame

I have an aspx page with a listbox control. The listbox is populated from a collection that is retrieved from a service when the page loads. When the user selects an item from the listbox the page posts back, adding the retrieved objects to the session before reloading. On the reload I use the session objects instead of having to call the service again.

This all works fine until I access the page from within an iFrame. The Session objects are not retrieved when the page is in an iFrame (Session["blah"] is null). This code works perfectly when the page is not in an iFrame.

I am using IIS7 and windows server 2008. Is there anything I need to do in ISS to allow Session variables to be used in an iFrame? Does anyone know of anything else that may cause this to happen?

Thanks, Neil

  • Actually never mind, I just cleared out the files in C:\Windows\Microsoft.NET\Framework64\v2.0.50727\Temporary ASP.NET Files and restarted IIS and it was all working
