[OmniFaces utilities (2.0)] Invalidates the current HTTP session

---

[OmniFaces utilities] The invalidateSession() method invalidates the current HTTP session. So, any subsequent HTTP request will get a new one when necessary.

---

Method:

See also: Faces#getContext()

Usage:

import org.omnifaces.util.Faces;

...

// before invalidate the session session ID may be: XY4i-kp_0NIDotbQaugGaM3P

String sessionId = Faces.getSessionId();

// invalidate the session

Faces.invalidateSession();

// after invalidate the session, Faces#getSessionId() will return null

String sessionId = Faces.getSessionId();

Note that the user principal is still present in the response of the current request, it's therefore recommend to send a redirect after #logout() or #invalidateSession(). You can use #redirect(String,String...) for this:

Faces.invalidateSession();

Faces.redirect(...);  // throw IOException
