Re: What is URL rewriting?

URL rewriting is the option when the client browser doesn't accept
cookies. The URL's are encoded in the form
"URL + ;jsessionid=4545". So, you can do response.encodeURL("/
servlet") to encode your URL's, but this will make effect only if the
browser doesn't accept cookies.

in the original post he said "...to keep track of users between

user information is usually stored as session object. We don't do such
things like url rewriting or cookies. But in those applications the
user has to login to the application before he can use it. That seems
to be the difference...

The session and session objects are stored in the server. Since HTTP
is stateless, you need ways to tell which session should be associated
with the HTTP requests the server receives. The server generate an
unique ID for each session, then send the unique ID to the user agent,
so that the user agent can send that ID back on its next request.

That's true if users log in through an HTML form.

If HTTP basic authentication is used instead of an HTML login form, the
user name is sent by the browser as part of the HTTP request headers, and
it can be used to identify the session.
