[squid-users] Acclerator mode

Hi all,

Using RHEL-3.1 x86, Squid-STABLE9 + Collapsed_Forward
patch.

I am try to set up squid as a surrogate to my back end
server which has an http service running on port
44003. What I' am seeing when multiple requests for
the same URI comes in that rather than allow just one
or two of the requests to go to the backend. So,
using a separate box, I setup multiple wgets (say 20)
to request the same URI ... each request initiates a
session to the back end. :(

Any thoughts about what is wrong with my test or the
config or hints about what folks usually goof up when
deploying squid as in Accelerator mode.

Thanks in advance for any help/suggestions,

Ray

Here is my squid.conf file
