Hi
My name is Wencheng Chai, my company are testing Squid on
Windows 2000 and try to get WCCP works on Squid. I have
developed a NDIS filter driver to decap. GRE packet. I have
noticed the difference between transparent proxy and
non-transparent proxy during my testing. In the case of
non-transparent proxy there seems to be two separate
tcp connections between Squid, original server, and IE 6.0.
If IE issues one GET, the connections will be closed after
IE get the page. However, the connections didn't get closed
if IE sent more than one GET to Squid. In any case, everything
works fine.
In the case of transparent proxy, if IE sent one GET, the behavior
is the same as non-transparent proxy. If IE sent more than
one GET, I noticed that there was one tcp connection for each
GET between IE and Squid, however there was only one tcp connection
between Squid and original server.
What I try to find out is that why my IE only get the first GET
displayed, but not the rest of the GET when Squid was configured
in transparent proxy more? I noticed that second GET over the wire back
to IE, but somehow the page didn't get displayed. so IE keep sending
GET requests. I would appreciate it if someone could verified
my observation and shed some light on how Squid handles transparent
proxy in term of tcp connection.
Thanks,
Wencheng
