[Haskell-beginners] cabal-install can't connect

Thanks, Salvatore.  I was able to get cabal install working by setting IE to use a local proxy server which is set up to cascade through to my corporate proxy.  I was already using CCproxy for testing some other proxy stuff internally, so that's what I used.  It works great!  I only use IE for those proxy settings now, and Firefox for my day to day browsing needs.

Thanks a bunch,

In my experience, cabal-install ignores the http_proxy variable on
Windows, and uses the Internet Explorer proxy registry key.
Another problem could be that your proxy is using NTLM authentication,
that cabal doesn't support.

To solve this problem, if your proxy supports BASIC authentication,
just put the proxy informations in the Internet Explorer proxy dialog;
you have to do it even if there's the "automatic proxy configuration"
setting, as cabal is unable to use it.

If your proxy supports NTLM authentication, just download a package
like http://www.geocities.com/rozmanov/ntlm/ and then put its host and
port as proxy in Internet Explorer.
