Suggested configure option on win32: for squid 3.0:

./configure --prefix=c:/squid --enable-win32-service \
--enable-default-hostsfile=none

for squid 2.7:

./configure --prefix=c:/squid --disable-wccp --disable-wccpv2 \
--enable-win32-service --enable-default-hostsfile=none

Or just use the official binary.

The installation of squid on windows is fairly easy, unpack the package, then:

build the cache:

C:\squid\sbin>squid -z

run in cmd mode:

C:\squid\sbin>squid

or install as service:

C:\squid\sbin>squid -i

note that C:\squid is the default prefix shipped with the win32 binary. For my self, I just need Squid configured for rsync proxy:

acl SSL_ports port 443 563 873 # 873 - for rsync
acl Safe_ports port 873 # for rsync

That's it!
