Enable Session State in SharePoint 2010

Posted on 8 June, 2012 by Krishana Kumar

Just Two entries we need to add in web.config file, when we use session state in SharePoint 2010 to store data for use in web parts, application page, etc. we may encounter the below given error if we not properly configured and enabled the session for the web application.

The error is :

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 fix this error and enable session state for SharePoint there are two entries we need to add for that web application.

First one – enable session state is set to True.

<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” asyncTimeout=”7″>

Second One- we need to remove and add lines exist in the modules section for Session

 

<modules runAllManagedModulesForAllRequests=”true”>

…

<remove name=”Session” />

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

…

modules>

After modified the web.config file with above two entries, we need to ensure that the Sate Service application is running. This can be check through Central Administration.

Now session Sate is enabled for our web application.
