Gzip troubles

matt · January 29, 2008, 10:34pm

IÂ¹m having a difficult time getting files (.js, .png) to gzip under my
configuration. Can someone tell me if IÂ¹m doing something wrong?

Django project

server {
listen 80;
server_name dev.foo.com;

    location ^~ /media {
        root /usr/local/backyardpost/trunk/static/admin;
        access_log   on;
        access_log /var/log/nginx/static_media.log download;
    }

    location ~*

^.+.(mpg|avi|mp3|swf|zip|tgz|gz|rar|bz2|doc|xls|exe|ppt|txt|tar|mid|midi|wa
v|rtf|mpeg)$ {
limit_rate 2000K;
access_log /var/log/nginx/django_media.log download;
access_log on;
}

    location / {
        fastcgi_pass 127.0.0.1:8080;
        include bots.conf;
        include     fastcgi.conf;
        access_log  /var/log/nginx/django.log  main;
    }

    # output compression saves bandwidth
    gzip  on;
    gzip_http_version 1.0;
    gzip_min_length  1100;
    gzip_comp_level 2;
    gzip_proxied any;
    gzip_types       text/plain text/html text/css text/xml

application/x-javascript application/pdf application/xml
application/xml+rss
text/javascript;

}

Seems like some things (HTML) are being gzipped by nginx automatically,
but
I have a JavaScript file being served at:
Foo.com that isnÂ¹t being
gzipped.
The file is 6.7K, so it doesnÂ¹t make sense to me. I have a CSS file at
Foo.com that supposedly is
being
gzipped (it is 6.3K).

Any idea whatÂ¹s going on?

Also, I am using Yahoo!Â¹s Yslow plugin for Firefox to detect what
components
are being gzipped. Should I be looking at something else instead?

Thanks,

Matthew

Look at the http headers during a request.
It is probably being compressed (the js files).

Not sure why you are trying to compress png and pdf files on the fly.

'Cause I’m a beginner. Thanks!

I do have that in the list. Are you saying to only have that one, or as
a
separate directive, or what?

do this:
curl -S -I -H “Accept-Encoding:gzip”
http://dev.foo.com/site_media/js/backyardpost.js

By the way, the backyardpost.css file header looks like this (I see the
â€˜gzipâ€™ in the Content-Encoding):

HTTP/1.1 200 OK
Server: nginx/0.6.16

Thanks again,

Matt

Adding â€œtext/x-jsâ€ to my gzip_content_types worked! Yay! Thanks.

Awesome tip! Thanks!

So maybe I need to add text/x-js to my list, not just
application/x-javascript?
