Option Name:nonhierarchical_direct
Default Value:nonhierarchical_direct on
Suggested Config:

	By default, Squid will send any non-hierarchical requests
	(matching hierarchy_stoplist or not cacheable request type) direct
	to origin servers.

	If you set this to off, Squid will prefer to send these
	requests to parents.

	Note that in most configurations, by turning this off you will only
	add latency to these request without any improvement in global hit

	If you are inside an firewall see never_direct instead of
	this directive.
