[SQU] accelerator question

Hello,

Any help appreciated!

I'm trying to set up a slow-server accelerator cache on port 80 residing
on the same machine as the main server (an Apache/mod_perl system, now
running on port 8080). The server is slow because it is a fully dynamic
app, and uses lots of memory to do its work; so squid seems a natural
speedup tool.

We host (currently) two sites using host-name (not IP-based) virtual
hosting. However, when trying to configure squid for this
configuration, it seems to force its connection not to the IP specified
in the httpd_accel_host line but to the Host: xxx specifier, which is
problematic because we run a server farm and none of the back-end
machines know their own DNS name. [ This also may be a security rules
violation, as I managed to get Squid to tap into a server using the
Host: header that was not within the acceleratedHost list specified in
the config file below. ] I need to be able to force only a connection
to a specific IP and have Squid request the virtual server using the
Host: header. How can this be done? I'm using Squid 2.3 STABLE4.

Thanks
