 * Did you get an answer on this? CDN url rewriting rules in w3 total cache are 
   ignored by the json api as well. I’d love to see them working together nicely.

 * Not by default in the plugin. The plugin only caches xml/html based pages. To
   support JSON data one needs to add and write a check for that in PageCache ob_callback.
   The use case has been noted however.

 * I solved this, although it’s not a perfect solution, but it works for now
 * I replaced `if ($buffer != '' && w3_is_xml($buffer))` in `PgCache.php` with
    
   if `($buffer != '' && (w3_is_xml($buffer) || w3_is_json($buffer) || w3_is_jsonp(
   $buffer)))`
 * The w3_is_json-stuff looks like this at the moment: [https://gist.github.com/3349372](https://gist.github.com/3349372)
