Session invalidation, using AJAX request data interception, the normal processing logic is to jump to the login interface, not the interface does not change (Java inference is Ajax request)

In the login filter. Request to infer whether the request is an AJAX request or a hyperlink or a change in the address bar

if (Httpservletreq.getheader ("X-requested-with")! = NULL
&& Httpservletreq.getheader ("X-requested-with"). Equalsignorecase ("XMLHttpRequest"))
{
Jsonobject jsessiontimeout = new Jsonobject ();
Jsessiontimeout.put ("Sessiontimeout", true);
Response.getwriter (). Print (jsessiontimeout.tostring ());
Response.getwriter (). Flush ();
Response.getwriter (). Close ();
}
else {
Gologin (Httpservletreq, httpservletres);
}

Js

/*******************************************************************************
* Infer if the session timed out. All dynamic requests need to be inferred

function Cheacksessiontimeout (data) {

if (Isjson (data))
{
if (data.sessiontimeout==true) {
Reload the address of the browser address bar and jump to the landing page
Window.location.reload ();
}
}
};

Cheacksessiontimeout (data) is called after all AJAX request data is successful;

$.post (
Url
{},
function (data)
{
Cheacksessiontimeout (data);
}
);
