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.

FAQ

Do I need a Peakhour account?

Yes you will need to sign up for the Peakhour service at https://www.peakhour.io/app/signup/,
all new domains get a free trial

Do I need to do anything else?

The service will work out of the box but you will probably want to start caching full pages by setting up
page rules, see our https://www.peakhour.io/support/page-rules/ guide to get started.
