1. Its not a transparent proxy.
2. My clients get wpad configuration from AD server. So there are two
question.
2.1 :I know that wpad is used to identify proxy server and port(and rest
other bypass rules). When clients resolve to wpad.abc.com, is there way
that I can overwrite the wpad file off client. Like creating a webserver to
to serve wpad file and I change /etc/hosts file to "<myhwebserveripaddress>
wpad.abc.com"
2.2 Is there any other way to tell clients via squid server, to do not come
to squid server and re initiate the request.
