Re: Serious bug, mixing mod-perl content
Beta contains new code and www is old code. We were calling www but once a
while beta would pop in. We noticed error messages that were giving whole
stack trace (caller) but those error messages were not present in www code,
they are implemented as a change in beta code. Right now we solved the problem
by moving beta to a totally different domain. We'll make a large test
eventually. Everything seems ok, double checked with a help from my business
partner, the paths are different, names are different etc.
Could you describe the actual nature of the error? How can you tell
that the response you're getting is from the wrong virtual host and what
is different about the virtual hosts' setup that causes the difference
in responses?

Are you sure you aren't just having namespace problems? If this code is in a module which has the same name for both versions, you can only have one version loaded in each perl interpreter. - Perrin
Re: Serious bug, mixing mod-perl content
Stas: I have 1.24 ver. of mod-perl and as I see
current Apache Registry sets $Apache::Registry::NameWithVirtualHost
explicitly to 1 if it's not defined (I've seen the sources).
These are apache's startup messages:
[Fri Mar 1 11:47:28 2002] [notice]
Apache-AdvancedExtranetServer/1.3.14 (Linux-Mandrake/2mdk) mod_perl/1.24
configured -- resuming normal operations[Fri Mar 1 11:47:28 2002]
[notice] suEXEC mechanism enabled (wrapper: /usr/sbin/suexec)
Ernest: I don't use server aliases but I'm going to
fix that. I wish that the problem is so simple. Actually the two virt. hosts are
beta.domain.com and www.domain.com
Christian: The setup is consisting of two httpd's,
one without mod-perl and one with mod-perl. First apache serves as a proxy to a
second one using mod-proxy and mod-rewrite. The second one is mod-perl enabled
and hosts Apache::Registry scripts. First one hosts plain cgi-scripts.On
both apaches there are two virt hosts, first apache one contains world viewable
virt. hosts and the second one contains internal virt hosts (accessible only
from 127.0.0.1, from first apache). The names and paths are different but the
error occurs, although it's very rare. I'm not using HTML::Mason here.
I noticed the error when I got error messages from
beta which contains new code and I was actually working with www.
tnx. for suggestions

Re: Serious bug, mixing mod-perl content
Are you using 2 separate apache processes or 2 virtual hosts within the
same apache process?
If it's the latter, according to Apache's documentation:
If no matching virtual host is found, then the first listed virtual
host that matches the IP address will be used.
(http://httpd.apache.org/docs/vhosts/name-based.html)
So it's possible that the client that is getting the wrong answers is
not specifying the Host: hostname parameter in the HTTP request and
Apache is therefore sending the request to the first virtual host.

I have virthost1 and virthost2 on mod-perl apache, most of the time you get the
right content when calling respective virthost but sometimes when you call virthost2
you get response from virt. host 1. This is a rare bug but happens.
We're using Mandrake Linux and it's 2 apache's (1 mod-perl enabled and the other
without mod-perl - this one uses mod proxy and mod rewrite).
Can someone please direct me how can I solve this problem ?

Hello Miroslav
Assuming, that you are using a handler, I ask you how you separate
each calls to your vhosts? I also assume that the vhosts are on the
same Apache runtime?
Probably you mix up namespaces ...
