- Open an account at a new host, preferably one who is specialist of distributed content. The most popular are Akamai (http://www.akamai.com/), Amazon (with its AWS services, among which is CloudFront: http://aws.amazon.com/) or CloudFlare (http://www.cloudflare.com/). You should also ask your own host, maybe it has a CDN service you can subscribe to.
- Copy your media files to that host's server. This means that the CDN server must contain an exact copy of the following folders from you store's main server:
/img
,/themes
and/modules
.
Reminder: you must make it so that these folders are always synchronized: even if you you add new products or change your theme, the CDN server must contain the latest version of all these files. - Once the CDN server is in place, add the web address (as given by your CDN host) in the first field, "Media server #1". If that host allows for more web addresses, add them.
...
- Create a subdomain for your store's domain name, for instance
http://cdn1.mystoreexample.com
(the way to do that depend on your host, ask him about it). Put a
.htaccess
file at the root of the subdomain. That file should contain a single line:Code Block Redirect Permanent / http://cdn-adresseadress.com
Replace thehttp://cdn-
with the one from your CDN server. This way, you are creating an automatic redirection from your subdomain to your CDN server.adresse
adress
.com- Once the subdomain is in place, add it in the first field, "Media server #1". If that host allows for more web addresses, create as many subdomains to your store's main domain name.
