Re: [squid-users] Help with accelerated site

It is a very stable piece of software that is used in production all the
time.

You have made a small mistake somewhere in your setup.

One of your errors in a previous e-mail seemed to indicate that you had
programmed a loop into your setup.

You might try uninstalling and starting over with an out of the box
configuration.

I would also start with only one way proxying and get that working.
If you are trying to act as an accelerator for your website, just do that.

That is a trivial setup.
You might also use Webmin to do the configuring since it gives you a gui
and avoids fiddling with configuration file syntax.

In my case, I have the proxy running on the same machine as the apache
webserver
accel defaultsite=www.artifact-software.com vhost

Squid listens on port 80 and tries to satisfy requests from its cache.

If it can not, it passes the request to port 127.0.0.1:81 where Apache
is listening with about 20 vhost sites including 2 proxies for Tomcats
on other backend servers.

Works great so I would not ge at all concerned that you will have
problems after you get your little misconfiguring fixed.
