Requests v1.2.3 doesn’t expose httplib’s support (since Python 2.7) for specifying the source address for binding the socket used by HTTPConnection:

• https://github.com/kennethreitz/requests/issues/995
• urllib3/urllib3#9

“This is what connection adapters are for.”

The example in adapter.py shows a basic implementation of a transport adapter that supports a src_addr keyword argument for specifying the source address. It has the following limitations because I did the simplest thing that could possibly work for my requirements:

• Requires Python 2.7+ for source address support in httplib or http.client.
• Not tested with Python 3.
• Supports only HTTPS.
• Doesn’t validate SSL credentials.
