The CP, intercepts requests on the tcp 80 and 443, if you type eg. http://www.foo.com, firstly starts a dns request for know the ip address of foo.com (lets say 1.2.3.4), then starts the request to htttp://1.2.3.4:80, if there is no internet connection, there is not the dns reply, and the http session won’t start.
