About sessionstate mode= ' InProc ' does not start asp.net service __.net

Because the ASP.net program is the default configuration, the session setting in the Web.config file is as follows:
<sessionstate mode= ' InProc ' stateconnectionstring= ' tcpip=127.0.0.1:42424 '/>

We will find that there is an attribute mode in the sessionstate tag, which can have 3 values: InProc, StateServer? SQL Server (case sensitive). By default, it is InProc, which means that the session is stored in the process (IIS5 is aspnet_ Wp.exe, and IIS6 is W3wp.exe), this process is unstable, and when certain events occur, the process is reset, causing the session loss stored in the process.
