URL Rewriting - Doubt

[kalle suresh]

In order for session to maintain there should be an unique sessionid that will be passed every time when the user sends the request and server responds back.
In case of cookies : first time the servers creates a session id and set cookie and when the user sends the request, the request will be sent with cookie header;

In case of URL Rewriting : The server appends the session id to the url by doing response.encodeURL(...).

But how the session id will be appended to the request URL?

But how the session id will be appended to the request URL?

A request parameter called "jsessionid" will be appended to the url. Here is an example from the servlets specification :

The session ID must be encoded as a path parameter in the URL string. The
name of the parameter must be jsessionid. Here is an example of a URL
containing encoded path information:
http://www.myserver.com/catalog/index.html;jsessionid=1234
