If it helps you at all, I might say that you're probably not alone with your
problem.

To me it seems that Katsuyuki Komatsu reports the same problem on entirely
different platform at "[ruby-dev:10985] httphead.rb proxy version problem".

  http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-dev/10985

Appended is a copy of something I could read from the mail (sorry if the
copy of japanese part is messed up).
