Yes this would be a nice feature I think... if storage is tight and
it's, eg, large html or JS that is needed, from lws device side this
costs no extra cpu with a client that can accept gzip (all browsers
afaik), and delivers the same data quicker with less bandwidth (for
text, with really quite considerable compression factors). The client
has to deal with it but often the clients are modern PCs or modern
phones / tablets that just shrug it off.

Yes I agree, I will take a look at it later today.

zlib is already integrated to lws for permessage-deflate ws extension fwiw.
