    • getAllowedVaryHeadersList

      List<StringMatcher> getAllowedVaryHeadersList()
       List of matching rules that defines allowed ``Vary`` headers.

 The ``vary`` response header holds a list of header names that affect the
 contents of a response, as described by
 https://httpwg.org/specs/rfc7234.html#caching.negotiated.responses.

 During insertion, ``allowed_vary_headers`` acts as a allowlist: if a
 response's ``vary`` header mentions any header names that aren't matched by any rules in
 ``allowed_vary_headers``, that response will not be cached.

 During lookup, ``allowed_vary_headers`` controls what request headers will be
 sent to the cache storage implementation.
