Draft: vhosts-in-depth and vhost-examples
Hi,
ok, here we go for a _first_ draft for the new vhosts-in-depth document
and a new vhost-example document containing some common (and maybe
uncommon ;-)) examples.
I'm currently not very happy with the vhosts-in-depth document, because
I'm still confused by some things (i.e. the fullURI stuff), but I
think Dean probably has some comments on the document. :)
The attachments include the documents in text format (I'll post the final
docs in HTML of course...).
ciao...

They don't need namevirtualhost. Unless you want to actually run a
name-based vhost on another port.

Oh interesting... I guess that bug got fixed at some point. It used to be
that "ServerPath /abc" would match /abcdef.

If we only deal with Port 80 we don't need an explicit Listen directive
(IMHO).

Ah, I forgot about localhost... but I think most servers are rarely access
as localhost. ,-)

You mean adding a _default_ vhost to very example? Well, I intentionally
added a paragraph about _default_ vhosts with example sections that can
be used in one of the other examples if they are need... and only when
they are need. If have a server with one IP and use it for name-based
vhosts (and also specify "NameVirtualHost 127.0.0.1 :-)) then a _default_
vhost (or the main server) never serves a request.

Ask Dean ;-)
My tests showed that it work without NameVirtualHost...

Yep, that's true.

Very good, Lars! I always missed an examples document!

How about "localhost"? It will be served by the supposedly unreachable
main server. Shouldn't the examples include _default_s or at least a pointer
to it?

Is it really true that Port based vhosts don't need a NameVirtualHost?
That was always unclear to me.

How about something along the lines of:
If the request is an absolute URI, and its hostname and port match the main
server or one of the configured virtual hosts, then the scheme/hostname/port
prefix is stripped of and the remaining relative URI is served by the
corresponding vhost. (If no configured main/virtual server matches the given
hostname and port, the request is taken to be a proxy request.)
If the request contained a relative URI, a similar search is made for the
value of the Host: header field.

^^^^^^^
I never tried this, but from looking at the code it appears to me that this
should read "ServerPath /abc/def"
Just my $.02

Ok I just posted some comments ... what I'd also like to see is for all
the vhost related documents to be moved into a new subdir
htdocs/manual/vhosts. This might make it easier to place and find all the
vhost info.
The fullURI stuff is obtuse and marginally broken, Martin is working on
a patch that makes it clearer and correct. We should wait for his patch
before documenting it.
