Subject: Re: Proxy Server troubles

I neglected to mention that if you use the proxy version of Net::HTTP,
you can get it to work without a proxy by putting in "" for the proxy
and port.  Here's the proxy version:

net = Net::HTTP::Proxy("proxy", "80").start(host)

and the non-proxy version:

net = Net::HTTP::Proxy("", "").start(host)

HTH,
Craig
