Add Name= "Stopappdomainrestartonfolderdelete"
Type= "Mywebsite.stopappdomainrestartonfolderdeletemodule"/>
It should be noted that "Stopappdomainrestartonfolderdelete" is a custom name, "Mywebsite" is a namespace in the above. cs file, typically the project name. " Stopappdomainrestartonfolderdeletemodule "is the class name in the above. cs file.

Configure the session to be saved under <system.web> as StateServer.

<sessionstate mode= "StateServer" statenetworktimeout= "20"
stateconnectionstring= "tcpip=127.0.0.1:42424"/>
