Forwarding from subdomain to port not working

Question

the problem:

I am running a Windows Vserver and on this server I'm running a standalone Grails app on port 8081, which means that when I open

localhost:8081 (local) or domain:8081

in the browser, I see the interface of the Grails app.

What I am looking for is a way to type

subdomain.domain

that forwards me to

domain:port

I have read that this can be done using a virtual host on Apache. I used the XAMPP Apache because I'm running XAMPP MySQL anyway. I added this line to the WIndows host file:

127.0.0.1 subdomain.domain

and this part to apache/conf/extra/httpd-vhosts.conf:

<VirtualHost  *:80>
    ServerName http://localhost
    DocumentRoot "C:/xampp/htdocs"
</VirtualHost>

<VirtualHost *:80>
    ServerName http://subdomain.localhost
    Redirect / http://localhost:8081
</VirtualHost>

What I expected:

• when I open domain I see the xampp admin interface

• when I open subdomain.domain I see the Grails app (as domain:port)

What happens:

• no matter wheather I open domain oder subdomain.domain I'm always forwarded to domain:port

What am I doing wrong?

Answer 1

Solution (no idea where the technical difference is):

<VirtualHost Server-IP:80>
    ServerName http://domain
    DocumentRoot "C:/xampp/htdocs"
</VirtualHost>

<VirtualHost Server-IP:80>
    ServerName http://subdomain.domain
    Redirect / http://domain:port
</VirtualHost>

I even didn't have to make any entries in the Windows host file. NameVirtualHost wasn't necessary either.
