I tests against http://www.charlesproxy.com/ already (since I don't have corp proxy), but those who need this feature please try it and let me know if it doesn't work for you.

Do we want to support this, or require it to be explicitly entered with --proxy? I haven't had to work behind a corporate proxy, but after a quick search using env.HTTPS_PROXY doesn't seem to be a common pattern.

[juliemr]

responding to myself. Looked around, did find a couple uses of this, so let's keep it.

LGTM

I've made a couple of minor modifications here: #968

The error handling for the request was not evaluating the error variable, thus silently swallowing any errors coming from the request module.

I also added support for both lower case and upper case environment variables, i.e. (HTTPS_PROXY and https_proxy). This is in line with what tools like npm use.

at first it didnt work for me.
How to solve? Set env variables as below:
$ set HTTP_PROXY=http://proxy.com:8080
$ set HTTPS_PROXY=http://proxy.com:8080
and then run your command
(in my case it was due to angular-seed, so when bower install ran, it picked up these variables)

Doesn't work for a couple of us. We tried HTTP_PROXY and HTTPS_PROXY and setting node config proxy and still get the error: Error: tunneling socket could not be established, cause=getaddrinfo ENOTFOUND 9091 9091:80. Other internet commands are working with the above proxy settings correctly
