Invalidating a session in java

A server can build on this base to provide additional features and capabilities.

For example, the Java Web Server has the ability to revert to using URL rewriting when cookies fail, and it allows session objects to be written to the server's disk as memory fills up or when the server shuts down.

When a session expires (or is invalidated), the object and the data values it contains are removed from the system.

Beware that any information saved in a user's session object is lost when the session is invalidated.

For example, if a server supports only cookie-based sessions and a client has completely disabled the use of cookies, calls to the if the session being accessed is invalid.The Session API is a subset of the Java Servlet framework.It centres around the Http Session object, which on the Servlet represents the "session of the client whose request is being processed".Many web servers also support session tracking based on URL rewriting, as a fallback for browsers that don't accept cookies. For a servlet to support session tracking via URL rewriting, it has to rewrite every local URL before sending it to the client.The Servlet API provides two methods to perform this encoding: This method encodes (rewrites) the specified URL to include the session ID and returns the new URL, or, if encoding is not needed or not supported, it leaves the URL unchanged.

The rules used to decide when and how to encode a URL are server-specific.
