[squid-users] reduce wan link traffic--> query

Dear squid gurus,

I have configured squid cache server for my organization.
Idea behind this is to reduce wan link traffic so that i can utilize
that bandwidth for other new customers.

Now i want to test wheather it is reducing the overall bandwidth or not.
my squidclient mgr_client_list tell me this

HTTP: 195075 Requests, 57193 Hits ( 29%)

So i guess hits is the bandwidth saving. M i right ?
if not then plz let me know i m wrong.
I want to test wheather my wan bandwidth has reduced the traffic or not?
How do i test?

I have kept mrtg on squid cache server on both lan and wan ethernet. and
i have kept mrtg on other router connected through squid server.

monitoring it tells me some similar values so i m stuck up that my squid
is caching or not and wheather i have reduced my wan link usage.

Any ideas...
Any help will be greatly appreciated.
