Faced with strange behavior of nginx in reverse proxy mode. There is web server 1 - the original source. web server 2 on nginx caching data in reverse proxy mode between web server 1 and users.
Web server 1 delivers content in maximum gzip compression:
gzip compressed data, max compression, from Unix
Web server 2 delivers content not in maximum compression:
gzip compressed data, max speed, from Unix, original size modulo 2^32 328219
It looks like web server 2 recompresses gzip, but gzip compression is disabled in the nginx config with the following directives:
gzip_proxied off;
gzip_static off;
gzip off;
May be somebody has experienced similar behavior?
Expected behavior: delivery content to the client from cache that we get from the original web server 1 (already in maximum compression)
