The <system.web> node for all sites that want to share Web. config is added first.

If StateServer is not 127.0.0.1 for the remote server, modify the entries in the session server registry for the remote server IP address IPAddress hkey_local_machine\system\ The value of the Allowremoteconnection key in CurrentControlSet\Services \aspnet_state\parameters is 1, where the port key controls the ASP. The service's listening port, which requires the restart of the ASP. NET State service to take effect after modification;
