Bug with Generic Mirror CDN custom files plugin URL rewriting

Hi Frederick,

I noticed a small problem when using a generic mirror CDN setup along with a custom content directory. To be fair it’s not really a bug, just a glitch with my weird setup.

The setup is like this:

content
 |--themes
 |--plugins
wordpress
 |--wp-includes
 |--wp-admin
 |--... etc...

So the wordpress install is in a subfolder on the same level as the new content directory.

In Cdn.php when you’re creating the regexes for custom you are adding the site path so in my case it only matches example.com/wordpress/content/plugins...

You can fix by changing lines 310-312 like so:

$regexps[] = '~(["\'(])\s*((' . $domain_url_regexp . ')?((?:' . w3_preg_quote($site_path) . '|/)(' . implode('|', $mask_regexps) . ')))~i';
if ($site_domain_url_regexp)
  $regexps[] = '~(["\'(])\s*((' . $site_domain_url_regexp . ')?((?:' . w3_preg_quote($site_path) . '|/)(' . implode('|', $mask_regexps) . ')))~i';

Just allows the site path to be ignored in this kind of setup.
