How to ALLOW on URL that is using different port than 443
By default the policy will no accept HTTP CONNECT for ports other than 443, hence a policy rule will need to be added to allow the traffic
Here is CPL code to allow the traffic going to www.example.com over port 5555
<proxy>
http.method=CONNECT url.domain=www.example.com url.port=5555 ALLOW
Please note that port 555 will need to be allowed as well on the firewall for the traffic to go through from the proxy to the upstream.
