-A robust configuration for Apache is possible but tricky; please Google around. (Or help update this Guide if you have a good example configuration for Apache.)
+Apache is also able to serve the [gzipped](http://en.wikipedia.org/wiki/Gzip) version of your assets; however, it requires a bit more work:
+
+```apache
+<LocationMatch "^/assets/.*$">
+  Header unset ETag
+  FileETag None
+
+  # RFC says only cache for 1 year
+  ExpiresActive On
+  ExpiresDefault "access plus 1 year"
+
+  RewriteEngine	On
+  RewriteCond %{HTTP:Accept-Encoding} gzip
+  RewriteCond %{HTTP_USER_AGENT} !Konqueror
+  RewriteCond %{REQUEST_FILENAME}.gz -f
+  RewriteRule ^(.+).(css|js)$ $1.$2.gz [QSA,L]
+</LocationMatch>
+
+<FilesMatch \.css\.gz>
+  ForceType text/css
+</FilesMatch>
+
+<FilesMatch \.js\.gz>
+  ForceType application/javascript
+</FilesMatch>
+AddEncoding gzip .gz
+```
+
+NOTE: You will need to make sure `mod_headers`, `mod_mime` and `mod_rewrite` are loaded; otherwise, the above configuration will fail.
