Alexis S. L. Carvalho <alexis@cecm.usp.br> [Wed, 01 Nov 2006 14:53:11 -0300] rev 3608
Use httpconnection even with proxies.
This should give us HTTP keepalive when we talk to proxies and
should allow us to stream a file in unbundle (instead of
reading everything into a string).
This should fix issue376.
