Option Name:url_rewrite_bypass
Default Value:url_rewrite_bypass off
Suggested Config:

	When this is 'on', a request will not go through the
	redirector if all redirectors are busy.  If this is 'off'
	and the redirector queue grows too large, Squid will exit
	with a FATAL error and ask you to increase the number of
	redirectors.  You should only enable this if the redirectors
	are not critical to your caching system.  If you use
	redirectors for access control, and you enable this option,
	users may have access to pages they should not
	be allowed to request.
