I've just started looking at using Squid for a project and can't seem to see an easy way of disabling the Squid error pages (e.g. "Name Error: The domain name does not exist"). We use a custom browser which handles that scenario in our way, so the Squid error pages are overriding our custom logic.

Is it possible to set them too 'off'? I've been through the .conf and I've found where the error pages are stored, but no real options to disable them.
