Rails - Aug 2009 - Stubborn 403 trying to use gems with proxy on windows cygwin

Hey all,

We''re on windows, using cygwin, behind a firewall with a proxy and
having difficulty (understatement) installing rails. It seems that no
combination of http proxy parameters and environment variables will get
this to work, all of them result in the output copied below. At the same
time, wget will download any of the listed files just file (with the
http_proxy env variable set).

Any ideas? Thanks a bunch!

So it seems as though my proxy is filtering based on User-Agent. I got 
gem to install rails by changing gem''s remote_fetcher.rb. In def
request
you''ll find

    ua = "RubyGems/#{Gem::RubyGemsVersion} #{Gem::Platform.local}"
    ua << " Ruby/#{RUBY_VERSION} (#{RUBY_RELEASE_DATE}"
    ua << " patchlevel #{RUBY_PATCHLEVEL}" if defined?
RUBY_PATCHLEVEL
    ua << ")"

I replaced all of this with a blatant lie:

    ua = "Wget/1.9.1"

and gem worked just fine, so it seems.

I know there are others around the World Wide Web that are having 
similar issues. Without knowing how many of them are caused by this 
issue: maybe it would be worth the little bit of effort to make 
User-Agent a gem parameter?

Live long and prosper,
Najati
