Custom Cache Key

Create a cache rule to set a custom cache key for all query string parameters, for any hostname containing example.com:

When incoming requests match: Custom filter expression
- Using the Expression Builder:
  Hostname contains "example.com"
- Using the Expression Editor:
  (http.host contains "example.com")
Then:
- Cache eligibility: Eligible for cache
- Setting: Cache key
  - Query string: All query string parameters

Refer to cache keys for more information on possible settings when configuring a custom cache key.
