how Server judge an Ajax Request belongs to a Session

[mentor]

When user is authenticated, the server store "UserName" in session. Then throug ajax, the user request another page which require authentication. How the ajax request tell the server that one has been authenticated, or how the server know it's from 'UserName"?

Should ajax set SessionId in Header or Cookie ? How to get and set the SessionId ?

I learned the browser could send back to server a sessionid, but I don't know how this should be done in JS.

I'm using JQuery, C#.

Post some code that we can have a look at. Have you tried setting the session id without Ajax and got it all working fine?

my ajax code usually (in firefox at least) will automatically pop-up a login box if needed. the browser should handle this, it not something to worry about in js.

ajax will use the page's connection to the server.
when your page's connection times-out, so does the ajax auth.

does that help?

So I see that ajax will use the page's connection to the server. That's Ok, Thanks !
