proxy variable needs http:// prefix

I am following the example, but my application (using the gRPC C++ API on macOS) seems to only work if

http_proxy=http://127.0.0.1:12345

is passed rather than

HTTP_PROXY=127.0.0.1:12345

Only the lower-case writing of http_proxy and only with the http:// prefix I can see output in grpc-dump (0.1.2).

Hmm yes I got a report that Python requires the same format. The environment variable syntax is very loosely specified unfortunately so many applications require different formats.
Looks like the lower case and http:// format is more common though. Let me check if that works with Go and I'll update the documentation/examples accordingly.

Thanks for the report!

You're welcome! I just found your project, and it could be really valuable for us!

Yup seems Go is quite lax with what formats it accepts for these environment variables.
I've updated the documentation and tests to use the more widely accepted format of http_proxy=http://... (efdf360)
