@Amos
Jeffries :
Q
. How does the IP correlate to the tv_ip, sysadmin_ip,
workstation_ip ACLs above?
A.
these are separate text files in the same directory,
containing ip lists.
Q.
Any difference with how those machines are configured to use
the proxy
A.
all the machines are in the same domain and network.
Q.
what version of squid-3.5.x is being used
A.
Squid 3.5.0.2 on Redhat Linux , packaged rpm is used.
Q. His
squid.conf does not contain anything that obviously restricts
that.So I am suspecting the problems some old-ish browsers and
OS have with POST messages and Expect headers
A.
On the same machine if i change it to use another windows
proxy server, it works fine.

Q.
slow uploads but in 3.5.X which I am almost sure was not fixed
yet
A.
while on other machines it is working fine.
@Yuri
Voinov
Q.

LAN and/or to mail servers. Often this can help
A.
Do i explicitly need to do so, if yes please tell me how.
