Web.KeepAlive
Time-outs for the web client are specified in the SessionState time-out and authentication
         time-out values in the FsOptivaWeb\Web.config file. 
You can turn off time-outs by specifying 1 for WEB.KEEPALIVE.
If you turn on WEB.KEEPALIVE, consider lowering the session state time-out. This reduces the load on your server’s memory.
