Feature: streaming responses

[hazcod]

Hi!

It would be nice if we could stream (pass chunks directly to the client instead of loading the full response locally) HTTP responses. This would greatly speed up large responses such as images or large binary files.

Yes, I actually find it weird to see the connection stall when downloading a large file. Why would a proxy be not able to handle arbitrary response sizes?

We need to pull in the response in order support modification. Request and response body modification is the primary use case for Martian.
