When you use StateServer mode in session state attributes, you can specify an additional attribute,
stateNetworkTimeout. This attribute specifies the number of seconds that a Transmission Control Protocol/Internet Protocol (TCP/IP) network request can be idle before the request times out.
This is useful if your Web server or your state server is under heavy stress and needs more time to complete network operations. If a Web server or a state server is under stress and cannot complete the task on time, event ID 1072 and event ID 1076 may be logged in the event log.
You can specify the
stateNetworkTimeout attribute in the Machine.config file or in the Web.config file of an application. For example, use the following code to include this attribute:
<sessionState
stateNetworkTimeout="15"
/>
