Responding with GZIP data

[jviotti]

Does uWebSockets attempt to read Accept-Encoding by default and respond with GZIP automatically if it is compiled with ZLIB support, or are applications expected to handle this themselves?

The server itself does not respond with compression for HTTP, but you could write a function that does. We could have HttpUtilities.h for such functions.

Having utilities for this case would be great!

Note that if you are on a fast enough network, e.g. your Gb/s LAN, compression (especially with zlib) is almost always a loss.
I didn't test with HTTP, but I tested with WebSocket and partial compression of the message, and the bandwidth at which compression is a win is quite low / slow. LZ4 was a little better, i.e. a win at higher bandwidth, but not at LAN speed even. FWIW.
