[Phpwiki-talk] Bug#168137: phpwiki: HTTP_HOST should be used instead of SERVER_NAME in config.php (fwd)

[Matthew P. <mj...@ie...>]

I've just gotten this bug report from a user of the Debian package of
PHPWiki (reproduced in part below; the complete bug report and all
subsequent discussion can be found at http://bugs.debian.org/168137).  As
all good users do, he's even produced a patch (attached) to correct the
problem as he sees it.

Is this a problem which the PHPWiki authors feel is a real problem?  The
patch should apply cleanly, and I'm going to apply and test it when I've got
a bit more free time, but I thought it best to get this out to the upstream
developers ASAP.

phpwiki uses $HTTP_SERVER_VARS['SERVER_NAME'] to build URLs. I believe that
$HTTP_SERVER_VARS['HTTP_HOST'] should be used instead. Many systems have more
than one name, and often the primary configured name is not resolvable from
outside. In my case, the server is normally named "server.internal-nis-domain",
but to be accessible via WWW it has an additional DNS entry calles like
"server.official-domain.de". SERVER_NAME resolves to the first, unreachable
name, whereas HTTP_HOST gives the right one (which has to be correct because
it is the name we called to reach the PHP script).

Maybe it would be possible to work around the problem by defining a VirtualHost
(untested), but I think changing the variable would be the right way because
HTTP_HOST is meant for this purpose.
