Usage:   deny_info err_page_name acl
	or       deny_info http://... acl
	or       deny_info TCP_RESET acl

	This can be used to return a ERR_ page for requests which
	do not pass the 'http_access' rules.  Squid remembers the last
	acl it evaluated in http_access, and if a 'deny_info' line exists
	for that ACL Squid returns a corresponding error page.

	The acl is typically the last acl on the http_access deny line which
	denied access. The exceptions to this rule are:
	- When Squid needs to request authentication credentials. It's then
	  the first authentication related acl encountered
	- When none of the http_access lines matches. It's then the last
	  acl processed on the last http_access line.

	NP: If providing your own custom error pages with error_directory
	    you may also specify them by your custom file name:
	    Example: deny_info ERR_CUSTOM_ACCESS_DENIED bad_guys

	Alternatively you can specify an error URL. The browsers will
	get redirected (302 or 307) to the specified URL. %s in the redirection
	URL will be replaced by the requested URL.

	Alternatively you can tell Squid to reset the TCP connection
	by specifying TCP_RESET.
