I never see the certificate cache link in Advanced URLs.
Where to find the SSL Proxy certificate cache?
The SSL Proxy Certificate cache can be found at -
https://x.x.x.x:8082/sslproxy/certcache
OR
https://<HOSTNAME>:8082/sslproxy/certcache
Where:
x.x.x.x = IP address of the proxy
HOSTNAME = Proxy's hostname
