Option Name:chroot
Default Value:none
Suggested Config:

	Specifies a directory where Squid should do a chroot() while
	initializing.  This also causes Squid to fully drop root
	privileges after initializing.  This means, for example, if you
	use a HTTP port less than 1024 and try to reconfigure, you may
	get an error saying that Squid can not open the port.
