Customer has configured emplty whitelist policy (i am not sure why they configured), In That polcy none of the url is present(its emply).
The rule like that,
Any Whitlist policy(empty) any any allow.
But when in check test the url category in the proxy its some of the urls are matching that empyt policy.
When i disable this policy that url is not working. even in that policy trace also it matches in that policy only.
