Subject: [users@httpd] Proxy Error 502 on one vhost and not the second

Good day there.

I'm using mod_proxy to redirect trafic to java applications running on
JBoss instances. I have 3 JBoss instances running seperate apps, the
redirects of 2 of these works fine with mod_proxy configuration but
the third doesn't.

The first 2 instances where set up a long time ago. I've used the one
instance's configuration file for the third one as it was close to
what I required. Here's the 2 configurations.

Working:

<VirtualHost *:80>
=A0=A0=A0 ServerAdmin developers@company.com
=A0=A0=A0 ServerName sub.domain1.com
=A0=A0=A0 ProxyRequests Off
=A0=A0=A0 ProxyPreserveHost On
=A0=A0=A0 ProxyPass / http://sub.domain1.com:18080/
=A0=A0=A0 ProxyPass /media !
=A0=A0=A0 ProxyPassReverse / http://sub.domain1.com:18080/
=A0=A0=A0 ErrorLog /var/log/apache2/domain1-error_log
=A0=A0=A0 CustomLog /var/log/apache2/domain1-access_log combined
=A0=A0=A0 <Directory "/srv/www/vhosts/domain1">
=A0=A0=A0=A0=A0=A0=A0 Options Indexes FollowSymLinks
=A0=A0=A0=A0=A0=A0=A0 AllowOverride None
=A0=A0=A0=A0=A0=A0=A0 Order allow,deny
=A0=A0=A0=A0=A0=A0=A0 Allow from all
=A0=A0=A0 </Directory>
</VirtualHost>

The one not working:

<VirtualHost *:80>
=A0=A0=A0 ServerAdmin developers@company.com
=A0=A0=A0 ServerName sub.domain2.com
=A0=A0=A0 ProxyRequests Off
=A0=A0=A0 ProxyPreserveHost On
=A0=A0=A0 ProxyPass / http://sub.domain2.com:28080/
=A0=A0=A0 #ProxyPass /media !
=A0=A0=A0 ProxyPassReverse / http://sub.domain2.com:28080/
=A0=A0=A0 ErrorLog /var/log/apache2/domain2-error_log
=A0=A0=A0 CustomLog /var/log/apache2/domain2-access_log combined

=A0=A0=A0 <Directory "/srv/www/vhosts/domain2">
=A0=A0=A0=A0=A0=A0=A0 Options Indexes FollowSymLinks
=A0=A0=A0=A0=A0=A0=A0 AllowOverride None
=A0=A0=A0=A0=A0=A0=A0 Order allow,deny
=A0=A0=A0=A0=A0=A0=A0 Allow from all
=A0=A0=A0 </Directory>
</VirtualHost>

The one that's not working I can browse to
http://sub.domain2.com:28080 without a problem but when I try to
navigate to http://sub.domain2.com I get the following error
irrespective of whether the server it's redirecting to is started or
not.

"
Proxy Error

The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET=A0/.

Reason: DNS lookup failure for: sub.domain2.com

Additionally, a 502 Bad Gateway error was encountered while trying to
use an ErrorDocument to handle the request.
"

I'm running on a SuSE and Apache 2.2.4 environment.

Mod_Proxy is loading properly as is evident by the already working
instances. I'm either missing the mistake in the vhost directive or
forgot about a configuration in another file.
