Handle custom proxy headers when making HTTPS requests in python
...We currently provide extensions to the following packages:
urllib3
requests
aiohttp
httpx
None of these modules provide good support for parsing custom response headers from proxy servers. And some of them make it hard to send custom headers to proxy servers. So we at ProxyMesh made these extension modules to support our customers that use Python and want to use custom headers to control our proxy behavior. But these modules can work for handling custom headers with any proxy.
