Configure Caching rules

If wordpress is not sending cache control headers, this plugin won’t, then caching rules need to be set up. The following are for a standard
wordpress information site. If you have additional functionality, eg woocommerce, then additional configuration will be required.

1. Continuing on from the configure cache settings section and find EDGE -> Rules in the left menu
2. As a safeguard add in three no caching rules.
   2.1 Enter ‘php’ as the rule name, ‘ends_with(http.request.uri.path, “.php”)’ as the filter, add the setting ‘CDN Status’ and select disabled. Save
   2.2 Enter ‘wp-admin’ as the rule name, ‘http.request.uri.path eq “/wp-admin/”‘ as the filter, add the setting ‘CDN Status’ and select disabled. Save

3. Add in the general caching rule. Enter ‘general page caching’ as the rule name, ‘ends_with(http.request.uri.path, “/”)’ as the filter, then add:
   CDN Status = enabled
   Strip Outgoing Cookies = enabled
   Strip Cookies from response = enabled
   Ignore Cache Headers = enabled
   Require Cache-Control for caching = disabled
   Browser TTL = don’t cache
   CDN TTL = 30 days

   Save

You can of course make the CDN TTL longer or shorter as required.
