RE: [squid-users] Using a helper program with squid

It sounds like you want a second proxy out on the internet that is
replicated with the data from the primary proxy server. If you explain the
purpose of the internet based server that is collecting cached information
from the main proxy, maybe that will help. i.e. is there another set of
users using this second cached server?

Thanks Lakshmi,

I think I understand your solution. But as I explained in my other response,
I need squid to "send the results it has for the client (coming either from
its cache or the original Web server), to another server, and read the
response from that server, and send that to its client."
I do want squid to contact the original Web server...

Sorry folks if you're tired of seeing the same question re-stated in several
emails.
