Im going to use maxcdn as my cdn provider with originpull but im not sure im doing everything right so far. I have created cdn.mydomain.com and received a cname record. What confuses me a little is do I upload my static content to cdn.mydomain.com ? Im mostly playing around but im going to do my first try later today...
Yes I believe. I am using Cloudflare and it takes care of everything from setting the cname and delivering the content. Not very sure about maxcdn. You can give cloudflare a try if you find any issue setting up the cdn.
