I've been working on this same problem -- proxying requests (POST is the 
troublesome one) while being able to handle non-well-formed XML 
responses. I had searched for a ready-made solution for this in Cocoon, 
and couldn't find one. Now I'm encouraged to hear from an expert like 
Bertrand -- it's not just because I'm incompetent. :-)

Anyway, Angelo, if you come up with a solution, I would love to see it 
too. Maybe it could be incorporated as an improvement to one of the 
proxy generators into the standard Cocoon package.
