How do I route Cloudfront with multiple origins?

Question

So I have 2 Wordpress sites hosted as such

• http://siteA.mydomain.com
• http://siteB.mydomain.com

I have a distribution created that has the 2 domains above as the origin.

• siteA.mydomain.com
• siteB.mydomain.com

I'm not sure how to configure the routes such that http://siteA.mydomain.com/wp-content/* will go to siteA's domain, and http://siteB.mydomain.com/wp-content/* will go to siteB's as the path pattern is the same.

Or should I create another distribution for siteB?

Solution

Create a second distribution.

CloudFront can select the origin server based on path pattern matching only -- not the hostname, or other request parameters.
