Topic: Apache Internal Server Redirection vhost => vhost not wor

[Smokin...]

Hi

Any help anyone can give me on this problem would be appreciated.

I have a Public [82.x.x.x] and Private Apache Servers [192.168.20.100], and wish to redirect a series of subdomain requests i.e. for joomla.example.com or moodle.example.com on 82.x.x.x => joomla.example.com or moodle.example.com on 192.168.20.100.

joomla.example.com [82.x.x.x] returns joomla.example.com [192.168.20.100]

moodle.example.com [82.x.x.x] however returns joomla.example.com [192.168.20.100]

VHOST Configuration on [82.x.x.x]:

<VirtualHost *:80>
ServerName joomla.example.com
RewriteEngine On
RewriteRule ^(.*)$ http://192.168.20.100$1 [P]
</VirtualHost>
<VirtualHost *:80>
ServerName moodle.example.com
RewriteEngine On
RewriteRule ^(.*)$ http://192.168.20.100$1 [P]
</VirtualHost>

The first VirtualHost section is used for all requests that do not match a ServerName or ServerAlias in any <VirtualHost> block.

Because you have no First/Default host as vhost in 192.xx it serves the joomla one. So with Joomla you are lucky.

Maybe helps that you add in 82.xx :

ProxyPreserveHost On

See.. http://httpd.apache.org/docs/2.4/mod/mod_proxy.html#proxypreservehost

Hi,

As suggested -

Added: 'ProxyPreserveHost On' to each of the [82.x.x.x] vhost files.

<VirtualHost *:80>
ServerName joomla.example.com
RewriteEngine On
ProxyPreserveHost On
RewriteRule ^(.*)$ http://192.168.20.100$1 [P]
</VirtualHost>

Works with no problems. Thanks
