I have nginx acting as reverse-proxy for an ASP.net

I'd like nginx to do gzip compression (ie, permessage-deflate / rfc7692) for my Websocket connections, but I can't find any config options for that.

Can nginx do that? Are there any plugins to make it work? If no, is there something else I can use?

just edit your nginx config. It is the same for static sites, proxies or websockets

gzip on; //enables gzip for request
gzip_proxied any; //enables compression on proxies
gzip_types *; //compress everything there is

if this does not work, try compressing the messages befor sending them through the socket.
