Regex is not compatible when `absolute_urls: true` is set.

[mdonadio]

Grav version: 1.3.10
CDN version: 1.4.0

If a Twig template uses the url() function to reference an asset, eg

<link rel="icon" type="image/png" sizes="32x32" href="{{ url('theme://images/favicon/favicon-32x32.png') }}">

then the final URL doesn't get updated to point to the CDN.

The problem is that if system.yaml has absolute_urls: true, then the the regex will skip them.

something like
<div style="background: url({{page.media[feature.background].url}});">.... }}
also doesn't get updated, despite 'absolute_urls:false'.
Is this the same issue or something else? It fits the original problem description.

Grav: 1.5.8
CDN: 1.5.0

OK, I see what the problem is with 'url()', the value does not need to be quoted and the Grav url() method doesn't include quotes. Unfortunately, your regex: https://regex101.com/r/8zAnec/2 requires quotes.
"/(url\([\'\"]?)... making the quotes optional solves mine and the original problem.
Hope this helps.

Can I suggest the following for line 83:
$regex = "/(url\([\'\"]??)(?:" . $base . ")(.*?\.(?:" . $extensions . "))(.*?\).*?;)/i";
Semicolon doesn't necessarily follow closing ) when used with background:
style="background:transparent url({{page.media[feature.background].url}}) center center/ 100% no-repeat;"
I hope that covers everything, but my regex knowledge is not great.
