This enables you to decide where you need sessions to be reside.

InProc - Session will reside on same computer memory where web application deployed

StateServer - Session will reside on other computer memory. you can specify the IP address of the PC

SQLServer - Session will be stored SQL server tables

InProc and OutProc is related to asp.net session management.
Session can be maintained in 3 different ways as seen below.

InProc - session kept as live objects in web server (aspnet_wp.exe).
Use "cookieless" configuration in web.config to "munge" the sessionId onto the URL (solves cookie/domain/path RFC problems too!)

StateServer - session serialized and stored in memory in a separate process (aspnet_state.exe). State Server can run on another machine

SQLServer - session serialized and stored in SQL server

Please refer:
in-proc,out-proc and sql server.[^]

Hi,

Inproc session mode,

1. session data is stored in current application domain and so consumes memory of server machine.

2. if server restarts, all session data is lost.

Out-proc mode (which is generally state server),

1. session data is stored on state server and so web servers memory is not consumed.

2. in case of web server restart, session data is preserved.

considering above points, use of session mode is the choice to be made considering load, no. of users, performence requirment etc.

for small web site with limited no. of users, in-proc mode is best suited.

for large applications with huge no. of users, state-server/sql server session mode should be used.
