Thanks all for replying! One question though:
I understand that I need to use the encodeURL() method - I use callPage(see
code block below) in my Servlets to load JSP files since I am using
Websphere 2.x and JSP version 0.91 - could I replace the callPage method
with the encodeURL() method?
HttpServiceResponse response = (HttpServiceResponse)res;
response.callPage("/ShoppingCartTotal.jsp", request);
cheers
marc

Subject: Re: Session testing question
If the user chooses to turn off their sessions for cookies you need to URL
rewritting, this is done by using
response.encodeURL(URL)
basically what URL rewritting does is change the URL to include a session
ID within it some where ie
http://fred.bloggs.com.au/fredspage.html
may become
http://fred.bloggs.com.au/fredspage.html?sessionid=XZXZX1234GDFSUE
the session id string is generated by the server you don't need to
know it. normally it would be in the cookie.
one problem is that you need to do this with every URL on your page !
As soon as the usesr takes a link that doesn't have rewriting on it you've
lost their session.
this is the same for servlets as for JSP you would do something like
<A href="<%= response.encodeURL("\fredspage.html") %>">freds page</A>
as for detecting if the user is using cookies you can do it but there is no
need, just use the above on all your URLs and the server will decide
if the URL's need to be rewritten or not.
another way of doing it is to parse your HTML through some other
code that will rewrite the URLs for you (this is how I've done this
with some code I wrote, I can send it if anyone wants it)
Hope that helps
