If you wish to have CacheFly proxy requests for dynamic pages back to your web origin, you'll need to ensure that the following is configured;
- Your web origin needs to be configured so that the Cache-Control: no-cache HTTP header is sent for dynamic pages.
- Create a CNAME record for CacheFly given delivery domain (e.g. username.cachefly.net). You can refer to this article for instructions on how to accomplish this.
- Create an DNS A record pointing your www.yourdomain.com to the CNAME alias created in the last step. It is also recommended that you create a redirect for your non-www domain name as well.
