What will happen to the session after redirect?

I would ask a general question:

What will happen with the Session, Log-in cookie in the case situation:

The case is Redirect from a web application to another then the second application to the first one?

A => B => A

Will the be persist or a new one will be created?开发者_如何转开发 or something other?

It will persist, so long as the session hasn't timed out (default 30 minutes)

The cookie will stay in the browser, but is application specific. So in your example, if application A deposited a session cookie on the clients browser, application B would not be able to access it. If application B then redirects back to A before the session times out, you will still be able to access it in application A.

It would be persisted until the session times-out.

If the transition from B => A happens in the timeframe where the Cookie Data and the Session are valid you still will be logged in.

Beware Session Lifetime != Cookie life time

If a site proves additional information you may be logged out though. E.g. Refererer or something like this.
