I am using squid proxy 3.1. I want to allow users to access particular domain urls only. Say allow only this url "https://google.com/search" through squid proxy. Default squid does not know the url because https request is encrypted. For that , I am using
ssl_bump to decrypt the

This acl is blocking all domains besides "google.com" but I can access any urls from "google.com". I am expecting to allow "/search" only.
