This question was asked back in 2010 @
Outputting Canonical Resource URLs Across a Multisite Network?
WordPress MU Domain Mapping @ WordPress.org
Since many things have changed since then, I was wondering what would be the best method to do this now. Would it be easier/better to just use .htaccess rules or in a varnish VCL?
I want to normalize plugin/theme files accross all of the sites on the network without using any host file hacks and works with the domain mapping plugin. I am using the subdirectory install and also a CDN. Thank you for any help/examples. This is my first post, but long time lurker 😉
P.S. If themes/plugins would need to be manually edited, would it be easier to create a plugin with all of the rules that can be network activated?
