Hey all, I’m running nginx 1.2.6 from a packaged install on Ubuntu 13.04. I’m at a total loss as to how this is happening but I simply cannot disable gzip compression for my server no matter what I try. Setting gzip off; in nginx.conf in the http context doesn’t work. I modified the default config setting that was already there. I even moved it to the bottom of the section to see if maybe there was something else that was toggling it on after that config entry. Is there something else I can look for that would be enabling gzip compression on my server? I saw there’s a static gzip compression module that’s optionally compiled in but that doesn’t seem relevant to my situation as this is a REST call. Here’s my response header from curl which does not appear to gzip compress: HTTP/1.1 200 OK Server: nginx/1.2.6 (Ubuntu) Date: Thu, 22 Aug 2013 00:08:26 GMT Content-Type: application/json Content-Length: 0 Connection: keep-alive P3P: CP=“CAO PSA OUR” Set-Cookie: jcid=5215567ae4b0861a8dd5c1dc;Path=/;[Domain=.foo.com](http://Domain=.foo.com);Expires=Fri, 22-Aug-2014 00:08:26 GMT;Max-Age=31536000 Expires: Thu, 01 Jan 1970 00:00:00 GMT ETag: “5215567ae4b0861a8dd5c1dc” However that same URL’s response headers in any browser (chrome, FF, safari) are as follows: Connection:keep-alive Content-Encoding:gzip Content-Type:application/json Date:Thu, 22 Aug 2013 01:39:24 GMT ETag:“521462bfe4b00dcc1c3b7c52-gzip” Expires:Thu, 01 Jan 1970 00:00:00 GMT P3P:CP=“CAO PSA OUR” Server:nginx/1.2.6 (Ubuntu) Set-Cookie:jcid=521462bfe4b00dcc1c3b7c52;Path=/;[Domain=.foo.com](http://Domain=.foo.com);Expires=Fri, 22-Aug-2014 01:39:24 GMT;Max-Age=31536000 Transfer-Encoding:chunked Vary:Accept-Encoding, User-Agent I’m certain that I’m doing something wrong but I’m out of ideas at the moment on what to check. Thanks for any insight or pointers anyone may be able to provide. Cheers! ---

My guess: If the compressed files are pregenerated and sitting on the filesystem (e.g. you have blah.json and blah.json.gz), nginx will serve them to any browser that sends the correct Accept-Encoding headers. Good luck.

Have you checked that there is no gzip at inferior levels (server or location blocks). Even better: gzip directive is internally set to ‘off’. Check that there is no ‘gzip’ usage anywhere in any included file of your configuration (simple grep) and you’ll have the conf you wish. ## 2nd part: Check your conf is _really_ applied on reload: first, check the syntax with nginx -t, then monitor the logs when reloading to see any error popping up. _B.
