Jeroen,

I'd like to avoid the slippery slope of deviations from the RFC given 
that this is supposed to be a RI (there's usually a gotcha somewhere 
along the line when one makes such devations). It may be equally simple 
to expect the caller to just encode the URI correctly. Lebing, you may 
want to check and see if there's a Java http url utility that can help 
with correctly encoding escaped characters.

Ranga
