Thanks Daniel,
I will try this approach. The reason for not putting things in the session
is that the system we are developing will probably have close to 2000 users
for the pilot, all permanently logged on during the working day. Each users
session object will get too big so all data to be passed over mutliple
requests will be encoded in XML on the HTML pages in hidden fields to be
passed to each servlet that needs to know as post parameters, which then
parse the XML.
I take it there is no way of passing a request object to individual frames
of a frameset page?
Cheers
Ian
