Post subject:  How can I point a subdomain to a specific folder?
Hi friends,

We have created an application to run on our server but which interfaces with a web application on another organization's server.
We got the the other organization to create a subdomain which point to our server's IP address.
(by the way, if you typed in our server's IP address, you''ll land on a default Apache/centOS page).

They pointed their subdomain to our server's IP address and now if a user goes to the subdomain, xyz.mydomain3.com, you'll be looking at our default Apache/CentOS page.

On our Linode server, the destination/where we have built the web application which the subdomain should be pointing to is mydomain2.com.

How can we point the subdomain, xyz (in xyz.mydomain3.com) to mydomain2.com?


Here's what our Linode DNS manager looks like:


Code:
DNS Manager ยป xyz.mydomain3.com

Primary DNS   Email   Default TTL   Refresh Rate   Retry Rate   Expire Time   Options
ns1.linode.com   myemail@gmail.com   Default   Default   Default   Default   Settings

ns4.linode.com   xyz.mydomain3.com   Default   Edit | Remove
ns5.linode.com   xyz.mydomain3.com   Default   Edit | Remove
Add a new NS record

www   123.45.68.90   Default   Edit | Remove

Add a new A record

Add a new CNAME record


TXT Records
Name   Value   TTL   Options
Add a new TXT record


SRV Records
Service   Domain   Priority   Weight   Port   Target   TTL   Options
Add a new SRV record

NOTE: Changes made to a master zone will take effect in our nameservers every quarter hour.


We would appreciate any helpful response.

Thanks.

In the Apache configuration section for mydomain2.com, you would add a line:

Code:
ServerAlias xyz.mydomain3.com


If you wished, you could instead use HTTP redirection (so that all requests for xyz.mydomain3.com get redirected to mydomain2.com) by setting up another VirtualHost just for xyz.mydomain3.com and using mod_rewrite.
