[squid-users] slow on a specific site

hi,

this is a problem that has been bothering me for so long now.. my
users connect to my squid machine, all sites that they visit are
'returned' ok and fast except for a particular site. the site is
www.esri.com. it is very slow when connecting to that site.. when i
try to connect to that site from the squid machine itself, it is fast.
the problem only comes when the computers connected to the squid
machine are to access that site.

any kind of help will be much appreciated.

Thanks!
