Can squid do the new style of virtual hosting, whereby you give a user
a CNAME alias to a web site, and the web site looks at the "Host:"
header supplied by the browser, and rewrites an address in the style
of into something like

I suspect this has to be done in the generic rewriting external
program. Are any extensions needed or are all the hooks there? Before
I write one, has anyone done it already?

Also on the subject of "Host:" rewriting - when a user fetches from such
a host using a squid cache, are those headers passed all the way back
up the chain? I'm worried they may get lost somewhere, say if a CERN
cache is a parent perhaps. It seems a very dodgy way of virtual
hosting; anyone know if it ever breaks?
