<p>“It’s important to make resources (images, scripts, stylesheets, etc.) cacheable.”</p>

<p>It is much easier to use a CDN without Query String Parameters.<br />
This plugins alters only local resources’ URL-s.<br />
The <code>ver</code> Query String Parameter will be inserted into the filename.</p>
<p>For example <code>jquery.min.js?ver=1.10</code> becomes <code>jquery.min.110.js</code>.</p>
<p>To reverse this in the web server add this line to your nginx config:</p>
<pre><code>server {
    location ~ ^(.+)\.\d\d+\.(js|css|png|jpg|jpeg|gif|ico)$ {
        #try_files $uri $1.$2 /index.php?$args;
        try_files $uri $1.$2 =404;
    }
}
</code></pre>
<p>Or to your Apache configuration or <code>.htaccess</code> file.</p>
<pre><code>RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)\.\d\d+\.(js|css|png|jpg|jpeg|gif|ico)$ $1.$2 [NC,L]
</code></pre>
<h4>Testing the plugin before live usage</h4>
<p>You can test the plugin by replacing the two <code>add_filter()</code> calls with this</p>
<pre><code>require_once( dirname( dirname( dirname( dirname( __FILE__ ) ) ) ) . '/wp-load.php' );
wp();
echo o1_revving_src( $argv[1] ) . PHP_EOL;
</code></pre>
<p>Then start it from CLI: <code>php revving.php <TEST-URL></code></p>

<p>Development of this plugin goes on on <a href="https://github.com/szepeviktor/resource-versioning" rel="nofollow ugc">GitHub</a>.</p>
