Session state can only be used when enableSessionState is set to true Error

Question

I have a SharePoint Web Application https://xyz.abc.net/sites/mob_portal with its Mobile Site URL as: https://xyz.abc.net/sites/mob_portall?Mobile=1

The normal site is working fine but when I open the mobile site URL I get the below error:

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 \\ section in the application configuration.

Can you please advise?

Answer 1

goto the webapplication web.config and search for enableSessionState and set it to true.

also make sure you have the moduel:

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

Answer 2

Set EnableSessionState=true in webapplication web.config file like :

  <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"> 

Also enabled session state from the web config by adding the http module
