CLI:

Hashurl policy priority is just higher than default policy.
The requests on a virtual service , which contains hashurl policies, will be directed to one of the groups associated with the virtual service through hashurl policy.

Note: the hashurl policies on the same virtual service are listed in order of policy name in the hash table of the virtual service.

Lookup:
(1) For a request on a virtual service v1, the Array TM will hash the url. We suppose the hash value hit policy p1 and group g1
Note: each request on v1 must hit one of the hashurl policies defined.
(2) If there is usable request in g1, the request will hit g1
If not, request will hit default policy on v1, and hit default group.
