David,

Thanks for your help.

I spent all last night trying to get it to work, but I can not work
out how to force my cookie into the response header.  The most
annoying part is on one occasion it did and the cookie sat there until
I killed the session.  By the time I discovered 'pageinfo' add-in for
firefox, the cookie had gone.

I have read a lot about cookies, but the grey matter is very slow at
absorbing nowadays.  I was wondering if I should add the 'path=/' to
my cookie, as I am using a host that has numbers for the IP address
and my domain name when used, is via a frame.  Although the python bit
to display the contents (when it did work), did not show any value for
'path'.

Could I create the response header in python and get it executed as
part of my form submission ?

Obviously, still struggling.
