Hi,
Super Cache says the following on their CDN feature:
Therefore, this plugin replaces any links in the wp-content
and wp-includes
directories (except for PHP files) on your site with the URL you provide below. That way you can either copy all the static content to a dedicated host or mirror the files to a CDN by origin pull.
Does this mean that if I add the domain, that I allocated to Super Cache, as a pull zone on Shift8 that they will work together? That both the allocated domain and the main website will both be pull zones?
Kind regards
