Cache Keys allow you to cache additional versions of a file for end-users that may request them.

Dynamic File Versioning

You can specify which parts of the end-user request should be used to build additional cache keys. Different parameters or headers will cause different versions of a file to be cached.

Additional Cache Keys By Headers

You can compile a list of headers to use as independent cache keys.

Additional Cache Keys By Query String Parameters

You can compile a list of query string parameters to use as additional cache keys.
