Hi Malcolm,
Thanks for your answer. Somehow I had a shortcircuit in my brain
yerterday that made me try to do an impossible upon the framework,
that is, using the same GET response with the same URL after an HTTP
redirect, rendering extra information if extra params in the URLconf
url were given. I finally realized that this was just impossible --
the one and only ways to pass info into an HTTP request is via GET or
POST params, or extra HEADers -- but anyway I am a passionate spirit
and sometimes I am blinded.
H.
