Displays Apache and PHP version in footer of admin section for easy access.
These information are usually needed if reporting bugs or checking hosting service configuration. WordPress displays only it’s own version which is not enough.
Plugin is very simple and uses almost no resources. After all, it just displays version information.

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

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