Access Restriction Public

Description

When we use a custom UrlRewrite module that does a RewritePath to an existing .aspx file you cannot use the Session Object in that .aspx page by default. The following exception is thrown by IIS7:
Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the <configuration>\<system.web>\<httpModules> section in the application configuration. 

Workaround:
Readd the Session Module under a different name in the <system.webServer><modules> collection. (must be removed again in web.configs of sub applications)

On installing Sharepoint 2010 the install completes and when the sharepoint configuration site is accessed I get this:

Error
Another component has already added an HttpSessionState to the context. Please make sure only one session state module should be registered.

I have a ULS viewer and not even does the correlation ID come up. Any ideas???

This behavior is by design.

I found a workaround to the 'Another component has already added an HttpSessionState to the context. Please make sure only one session state module should be registered.' issue: Add <remove name="Session"/> before the second session module tag.

Hi ,
I'm facing this problem too.
I added the Session module as sugested, that works fine , but it causes a problem on pages that do not use RewritePath ( like default.aspx for example)

'Another component has already added an HttpSessionState to the context. Please make sure only one session state module should be registered.'


Any idea what to change?
