I am trying to install cabal behind a firewall without success. It seems that cabal does not support http redirect, is there a way to fix it?
cabal update -v3

Follow @Sibi suggestion, I pasted a similar experience using cntlm-0.92.3.
Here is my config config.ini:
Proxy proxy.swmed.edu:3128 Listen 127.0.0.1:53124
I first tried to use:
./cntlm -c config.ini
then the same error happens:

NOTE: this question is not the same as authentication, as our proxy server does not need to be authenticated. This question is about http redirect problem.

Run the following command as @Sibi suggested:
./cntlm -M http://www.google.com -c config.ini -v
And the output can be found at http://pastebin.com/zAvZBDVu
Reading the logs, we see the proxy was via https not http, and the error was "unsupported scheme" since cabal prior to recent versions did not handle https. Https transports have been added to cabal in the most recent versions, so the issue should now be resolved.
