Enumerating Session Management Techniques

Before we proceed, let us see what all session management techniques are present in the ASP.NET framework.

·         In-Proc.

·         SQLServer.

·         StateServer.

How to configure Sessions

To configure the session management we need to specify the settings in the web.config file. Typical settings inweb.config looks like:

 Collapse | Copy Code

<sessionState mode="InProc" 

                stateConnectionString="tcpip=127.0.0.1:42424" 

                sqlConnectionString="Data Source=.\SQLEXPRESS;Trusted_Connection=Yes;" 

                cookieless="false" 

                timeout="100"/>

Let us see what each of these attributes mean.

Mode	This specifies the type of session management we want to use. it could be InProc,SQLServer, and StateServer
stateConnectionString	If we use StateServer as session management technique then this specifies the location of the server that is handling the session data.
sqlConnectionString	If we use SQLServer as session management technique then this specifies the databaseconnectionstring that will store the session data.
cookieless	This specifies whether we will be using cookies to identify sessions or we want session info appended in URL. It could be true or false.
Timeout	This specifies the time for which the session should be active. after this much time of inactivity the session will expire.
