  - Your model , on networking is negatively bended : in fact your question
is irrelevant to 'basic' SQUID, because it sits that app. layer in the
networking stack.
Clients forward http requests to SQUID, which squid handles , for instance
cached or not, in the latter case contacting the remote webserver and fetching
the requested object.
This could even be done , with any transport/networking implementation, and
must be seen separated from the app. layer.

Transparant proxy-ing may be an exception, indeed, but the consequences of
not obeying the network-layered-model has many possible caveats.
