I've tested a fairly wide variety of proxies with co-advisor; the only  
one that passed the related set of tests was very recent builds of  
Squid (2.7DEVEL0). Everything else -- including Squid 2.6STABLE4 --  
failed (it would take some digging to figure out exactly where this  
happened, unless Henrik knows; regardless, I think it's safe to say  
that a very large proportion of Squid's installed base fails as well).
