Gzip working for html, but not javascript or css (Apache)

Question

On my site, the html files are gzipped.

However, the javascript, css, and svg files are not.

The server uses Apache/2.2.22.

I'm using the .htaccess file from HTML5boilerplate. Here's the relevant section:

<IfModule mod_filter.c>
    AddOutputFilterByType DEFLATE "application/atom+xml" \
                                  "application/javascript" \
                                  "application/json" \
                                  "application/ld+json" \
                                  "application/manifest+json" \
                                  "application/rdf+xml" \
                                  "application/rss+xml" \
                                  "application/schema+json" \
                                  "application/vnd.geo+json" \
                                  "application/vnd.ms-fontobject" \
                                  "application/x-font-ttf" \
                                  "application/x-javascript" \
                                  "application/x-web-app-manifest+json" \
                                  "application/xhtml+xml" \
                                  "application/xml" \
                                  "font/eot" \
                                  "font/opentype" \
                                  "image/bmp" \
                                  "image/svg+xml" \
                                  "image/vnd.microsoft.icon" \
                                  "image/x-icon" \
                                  "text/cache-manifest" \
                                  "text/css" \
                                  "text/html" \
                                  "text/javascript" \
                                  "text/plain" \
                                  "text/vcard" \
                                  "text/vnd.rim.location.xloc" \
                                  "text/vtt" \
                                  "text/x-component" \
                                  "text/x-cross-domain-policy" \
                                  "text/xml"

</IfModule>

For what it's worth - it's not related to subfolders. If I put a file named "test.html" in the main directory - it's gzipped. If I rename it "test.js" - it's not.

[UPDATE]

So, this was dumb.

As I mentioned, I was using the .htaccess file from html5boilerplate.

When I looked at that closely, I noticed these notes:

# (!) For Apache versions below version 2.3.7 you don't need to
# enable `mod_filter` and can remove the `<IfModule mod_filter.c>`
# and `</IfModule>` lines as `AddOutputFilterByType` is still in
# the core directives.

This applies to me, since the server uses Apache/2.2.22.

Sure enough, as soon as I removed <IfModule mod_filter.c> and <IfModule mod_filter.c>, everything worked as it should have (i.e., the javascript, css, and other file types included in that list were all gzipped.

I'll leave this question, just in case anyone else makes the same mistake I did.

Check the rest of your config for "gzip-only-text/html"? Or other SetOutputFilter? Or perhaps this .htaccess is not read at all and defalte is setup elsewhere? — covener, Dec 04 '15 at 15:59

It looks like you missed something:

AddType image/svg+xml .svg

AddOutputFilterByType DEFLATE image/svg+xml
