The directive gzip\_static does not follow the rules in gzip\_types ``` gzip on; gzip_static on; gzip_http_version 1.0; gzip_disable "MSIE [1-6]\.(?!.*SV1)"; gzip_comp_level 5; gzip_min_length 1000; gzip_vary on; gzip_buffers 64 16k; gzip_types text/plain application/xml text/css ``` application/javascript application/x-javascript text/javascript; #strace open(“/var/www/forum/images/smilies/attention.gif.gz”, O\_RDONLY|O\_NONBLOCK) = -1 ENOENT (No such file or directory) open(“/var/www/forum/images/smilies/lookoutbelow.gif”, O\_RDONLY|O\_NONBLOCK) = 319 open(“/var/www/forum/images/smilies/lookoutbelow.gif.gz”, O\_RDONLY|O\_NONBLOCK) = -1 ENOENT (No such file or directory) open(“/var/www/forum/images/smilies/heresyoursign.gif”, O\_RDONLY|O\_NONBLOCK) = 320 open(“/var/www/forum/images/smilies/heresyoursign.gif.gz”, O\_RDONLY|O\_NONBLOCK) = -1 ENOENT (No such file or directory) open(“/var/www/forum/images/smilies/woohooo.gif”, O\_RDONLY|O\_NONBLOCK) = 321 open(“/var/www/forum/images/smilies/woohooo.gif.gz”, O\_RDONLY|O\_NONBLOCK) = -1 ENOENT (No such file or directory) open(“/var/www/forum/images/smilies/ohno.gif”, O\_RDONLY|O\_NONBLOCK) = 322 open(“/var/www/forum/images/smilies/ohno.gif.gz”, O\_RDONLY|O\_NONBLOCK) = -1 ENOENT (No such file or directory) As you can see, it is looking for .gz images even though the gzip\_types excludes images.

Thanks for the quick reply. It would be nice if there was a simple top level directive added to make it follow the gzip\_types rule. The default behavior of trying to compress images is pretty futile. Even if I had my bash script compress images to serve up, the extra decompression time on the client would cause the page to be slower, and bandwidth savings of probably less than 1% at expense of much, much more than 1% increased client CPU.

It doesn’t try to compress anything, it’s up to you to compress files you think is ok to compress. The gzip\_static just checks if a ‘.gz’ file present, and returns it to client if it’s present (and client supports gzip). If you want to avoid file lookup, you may (and probably should) disable gzip\_static for locations you don’t want lookup to happen. Maxim D.
