Thanks Maik and Paul, but I am still confused.
I have a number of independent Zope instances, call them zope0, zope1, zope2 all residing on the same machine, each front-ended with pound. Incoming requests are distributed by pound, based on the domain name
alpha.mydomain.com beta.mydomain.com gamma.mydomain.com
to zope0, zope1, and zope2, respectivelys. The DNS maps all of these domains onto the same IP address. Zope0, zope1, and zope2 are mapped to independent (IP-address, port) pairs by pound. In my non-working test case, they go to 127.0.0.1:8080, :9080: 7080.
Now, an instance of zope, for example, zope1, needs to construct an absolute URL. The incoming request has been remapped by pound and appears to have originated at 127.0.0.1:9080 but the absolute URL that's needed is http://beta.mydomain.com/.... I don't see how the virtual host monster makes this play. (I do see how it could be used to do virtual hosting at each individual instance of Zope, but that's not what I want to do.)
You confuse between IP address and request host. The VHM (or any system like it) does not care in the least about what address a name resolves to - all they look at is what host was the request sent to. As you read in earlier replies, all you need to do is to map (in VHM) between a host NAME and a Folder. If you use Pound to separate between hosts (which is not really necessary) you only need one mapping in the VHM, but you can have as many as you wish.
Would I be better off were I to bind the zope instances to local addresses, say 10.0.0.1, 10.0.0.2, and 10.0.0.3 and make suitably adjust named to return the qualified domain names?
No. Your current setup is fine.
Presumably Zope does a gethostbyaddr() to find its domain.
