Is My Site Cached (.com) Official Page

ismypagecached.com detects your "page caching" configuration and current state. The goal: to save you a little bit of time and keep developers focused 😇

We try supporting as many page-caching systems as can be detected, across multiple layers. Feel free to report issues and add feature requests. When reporting an issue, we need:

1. Description of the issue
2. Link for testing
