Hi Andrea,
first of all, could you please upgrade to v2.1.1? :)
You were looking at the right docs, and the "redirect_n"
property of <virtual-server> is your best bet for what you are trying to
achieve,
but I'm afraid that it does not completely address your requirements.
For starters, you could add this property to the <virtual-server> with
id "server"
in your domain:
<property name="redirect_1" value="from=
url-prefix=
http://www.domain.com"/>
Note the empty "from" value.
This will cause any request targeted to the root context of any domain
served by your http-listener-1 to be redirected to
http://www.domain.com, as in:
http://olddomain.com ->
http://www.domain.com
http://www.olddomain.com ->
http://www.domain.com
which is what you want.
A "from" value of the form "/", as in
<property name="redirect_1" value="from=/
url-prefix=
http://www.domain.com"/>
is equivalent to "/*" and is supposed to match a URI subtree, which it does
under certain conditions, but it was causing redirects in an infinite
loop (because
"/" matches any (redirect) URI), so we had to find a way to break out
from the loop,
at the cost of making "/" less useful. I think we went a little too far
there.
I have a one-line fix available for v3.1 (and possibly v3.0.1) which
does exactly
what you are looking for, but given that you are on v2.x, it may not be
of too much
help to you (unless you have a support contract for GlassFish, in which
case the fix
could be backported to a v2.1.1 patch release).
