Cookie is the way to go.
Look at
javax.servlet.http.Cookie
javax.servlet.http.Response.addCookie
javax.servlet.http.Request.getCookies
Set the max age of the cookie to be -1.
So: Each call: look for your cookie in the array you
get back from the request. Sadly it's an array, not a
Map.
If there is no cookie, create one with max age -1
and add the cookie to the response.
Voila.

Subject: [Tapestry-developer] [OT] need a quick cookie pointer
Have an oppotunity to make a quick score formy employer. Customer needs to
know if a visitor has been to a page (served by a Servlet)before. If the
user is new they will need to fill out a form.
I'm thinking cookie. Anybody know how to work with cookies in a Servlet? I
never needed to before.
Sorry this isn't Tapestry related, but you people are Extra Servlet-Aware!
:-)
If I can pull this off it'll go a long way to getting a little less pressure
here at work to
stop spending so much time working on Spindle. Free time is a luxury and
*everyone* wants some of it!
