In version 2.3 I've exposed a transport parameter that you can pass with your custom transports. I'm not sure it makes sense to bundle particular transports in the library, but you should feel free to put it in a separate package and upload it to PyPI for easy sharing and consumption.

Hello Max,

Have you had a time to fix the proxy issue ?
I need to use the code via proxy, could you help me please.
Thank you.

In my previous comment I said that I released version 2.3 with a new 'transport' parameter to the constructor that allows you to pass your own transports. You can even use the ProxiedTransport you had included in this pull request.

I haven't merged this PR because I'm not yet comfortable shipping transports as part of the core library itself. So instead I've made it simpler for users to supply their own.
