WebResource.axd going over HTTP when you are browsing on HTTPS

Sherlock Homes once said “It is a capital mistake to theorize before one has data”. Being in the business of troubleshooting, I for one, believe in this.

ASP.NET 2.0: AcquireRequestState fires multiple times

PROBLEM/TROUBLESHOOTING=========================I came across this problem while troubleshooting a “Session Loss” issue. Customer in this case was using the Application_AcquireRequestState method and within this method was trying to use the HttpContext.Current.Session object to do something with it.
