How do I clone a repository when I'm behind a proxy?
It's actually an environment variable, so try
http_proxy=http://proxy_server:4242 hg ...
You should replace 4242 with whatever port your proxy is running on.
I can successfully use the following command:
hg clone <TheURl> <Optional Folder Name> --config http_proxy.host=<proxy URL>
And obviously by replacing any <> instances with the relevant details.
You can setup proxy authentication in .hgrc file.
It store in ~/.hgrc. Here is an example.
[http_proxy]
host=hostname:port
user=username
passwd=password
Note: I currently use SourceTree app on Mac OSX.
