Set an absolute limit on the number of connections a single
	client IP can use. Any more than this and Squid will begin to drop
	new connections from the client until it closes some links.

	Note that this is a global limit. It affects all HTTP, HTCP, and FTP
	connections from the client. For finer control use the ACL access controls.

	Requires client_db to be enabled (the default).

	WARNING: This may noticeably slow down traffic received via external proxies
	or NAT devices and cause them to rebound error messages back to their clients.
