cache_​key_​query_​params

By default, cache keys are formed as URLs with full query strings. This behavior allows you to consolidate cached objects based on specified sets of query parameters.

Note also that whenever you apply behavior that generates new cache keys, your origin server may experience traffic spikes before the new cache starts to serve out.

behaviorenum

Configures how sets of query string parameters translate to cache keys. Be careful not to ignore any parameters that result in substantially different content, as it is not reflected in the cached object.

INCLUDE_​ALL_​PRESERVE_​ORDER
Forms a separate key for the entire set of query parameters, but sensitive to the order in which they appear. (For example, ?q=akamai&state=ma and ?state=ma&q=akamai cache separately.)
INCLUDE_​ALL_​ALPHABETIZE_​ORDER
Forms keys for the entire set of parameters, but the order doesn't matter. The examples above both use the same cache key.
IGNORE_​ALL
Causes query string parameters to be ignored when forming cache keys.
INCLUDE
Include the sequence of values in the parameters field.
IGNORE
Include all but the sequence of values in the parameters field.
parametersstring array 
Specifies the set of parameter field names to include in or exclude from the cache key. By default, these match the field names as string prefixes.
