When? To what type of URL?

Denies a client access to some traffic ...

Asks Squid to perform a URL-redirect to http://google.com instead of
delivering error pages when ACL "deny custom" happens.

... denies Squid permission to deliver your custom URL-redirect to the

Two problems. The one mentioned above.

Plus the fact that Browsers refuse to display or do anything for non-200
status responses to CONNECT tunnels. Whenever Browsers access https://
URLs through the proxy they use CONNECT tunnels.
