Keep in mind that clustering does not mean high availability. CLustering is sharing resources with multiple machines. What you need to look into is syncing and failover mechanisms so that 2 web servers at different locations are mirrored copies so that if one goes down, dns is routed to the other server.

I am kind of down this route myself and learning as I go. Be nice to utilize an HA consultant as trial and error can be costly.

cachemgr.cgi

cachemgr.cgi(8) 					      System Manager's Manual						   cachemgr.cgi(8)

NAME

       cachemgr.cgi - squid HTTP proxy manager interface

SYNOPSIS

       http://your.server/cgi-bin/cachemgr.cgi

DESCRIPTION

       The  cache  manager (cachemgr.cgi) is a CGI utility for displaying statistics about the Squid HTTP proxy process as it runs. The cache man-
       ager is a convenient way to manage the cache and view statistics without logging into the server.

FILES

       ./cachemgr.conf
       @DEFAULT_CACHEMGR_CONFIG@
	      The access configuration file defining which Squid servers may be managed via this  cachemgr.cgi	program.  Each	line  specifies  a
	      server:port followed by an optional description

	      The  server  name  may  contain  shell wildcard characters such as *, [] etc.  A quick selection dropdown menu is automatically con-
	      structed from the simple server names.

	      Specifying :port is optional. If not specified then the default proxy port is assumed. :* or :any matches any  port  on  the  target
	      server.

SECURITY

       cachemgr.cgi calls the requested server on the requested port using HTTP and returns a formatted version of the response. To avoid abuse it
       is recommended to configure your web server to restrict access to the cachemgr.cgi program.

       Configuration examples for many common web servers can be found in the Squid FAQ.
