Roland Weber commented on HTTPCORE-139:
---------------------------------------
Hi Oleg,
if you put the check in getParameter(), then classes like ClientParamsStack
that reference HttpParams can no longer distinguish between an unset parameter
and one set to an explicit null. I've mentioned that problem under Option A in
my post to the dev list:

cheers,
Roland
