There is no redirect unless you specify an external URL location in
deny_info.
Use a static template / filename at that will be injected as the
delivered object.

In the latest Squid you can supply an alternative 4xx error code and a
template in deny_info.
ie. deny_info 499:/etc/squid3/Kittens all

That is an entirely different problem to the one you have been talking
about so far.

To replace just the page Squid is generating you do not have to
configure anything. Just remove all the installed
errors/*/ERR_BAD_GATEWAY translation files, and replace the
errors/templates/ERR_BAD_GATEWAY one with your custom static page. You
can optionally provide translated versions of your custom page too of
course.
