In a project, you need to make the session variable exist in the whole cycle before the page is closed, and try to implement it using asp.net ajax. The Code is as follows:
On the. aspx page, <body> tag: <body onload = "KeepActive ();">
Client JS Code:
Function KeepActive (){
PageMethods. KeepSession ();
SetTimeout ("KeepActive ();", 600000 );
}
Background. cs code:
[System. Web. Services. WebMethod]
Public static void KeepSession ()
{
}
The purpose of the code is to allow the client to regularly call the server method so that the session status is not limited by the Session Timeout setting. From the actual running effect, most of the time can achieve the expected purpose. However, as we all know, sessions will be lost in some cases, so this method is powerless for Session loss due to non-timeout.
