IIS 6.0 Not loading SessionState for .NET 3.5 Application using HttpHandler

QA and Dev enviroments work perfectly. Handlers all implement the IRequiresSessionState marker.

Config File con开发者_开发知识库tains:

<pages enableSessionState="true">

and

<sessionState cookieless="AutoDetect" mode="InProc" timeout="20" />

IIS has session state enabled in application properties and Application is running in its own Application Pool....

So big difference in IIS 6 vs IIS 7.

The Session module need to be stated in the httpModules config section, as VS2008 adds a , and adding it to the web.server section does nothing...

<add name="Session" type="System.Web.SessionState.SessionStateModule"/>
