    <h1>Manually gzip CSS and JS files and serve them with Apache</h1>

    <p>A Compress all the files first. Run the command:</p>

    <pre>gzip -r *.js *.css</pre>

    <p>This will find all the Javascript and CSS files in the current directory and its subdirectories. They will be compressed into new files with a .gz extension added (ie, script.js becomes script.js.gz, there will not be a script.js left).
    </p>

    <p>Now edit .htaccess:</p>

    <pre>

    RewriteEngine on
    RewriteCond %{HTTP:Accept-encoding} gzip
    RewriteCond %{REQUEST_FILENAME}\.gz -s
    RewriteRule ^(.*)\.(js|css)$ $1\.$2\.gz [QSA]

    RewriteRule \.css\.gz$ - [T=text/css,E=no-gzip:1,E=manualgzip:1]
    RewriteRule \.js\.gz$ - [T=text/javascript,E=no-gzip:1,E=manualgzip:1]

    &lt;ifmodule mod_headers.c&gt;
    # setup this header only if rewrites above were used
    Header set Content-Encoding "gzip" env=manualgzip
    &lt;/ifmodule&gt;

    </pre>
