So let’s begin…

The concept

If you are trying to use session state in SharePoint 2010 to store data for use in web parts, application pages, etc. you may encounter the error below if session state is not properly configured and enabled for the web application.

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 \\<...

To resolve the error and to enable session state for SharePoint we need to follow the steps given below.

Steps for Enabling Session State in SharePoint 2010

1.    To enable Session State  first add the SessionStateModule to the  web.config file as shown below:

2.      Ensure that enableSessionState is set to TRUE as follows:
<pages enableSessionState="true" enableViewState="true" enableViewStateMac="true" validateRequest="false" pageParserFilterType="Microsoft.SharePoint.ApplicationRuntime.SPPageParserFilter, Microsoft.SharePoint, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c">

3.      Then, you must go into your web application and add the same session state module to the IIS7 managed pipeline.

i.        Open IIS 7 manager, and find your web application.

2. Double click "Modules" in the IIS section.
3. Click "Add Managed Module..." on the right hand pane.
4. In the Add Managed Module dialog, enter "SessionState" or something like that for the name, and choose the following item from the dropdown:

System.Web.SessionState.SessionStateModule, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a.
