Mystery redirect of domain.com to https://www.domain.com - what could be causing it?

Question

I am using apache on Centos and whenever I use domain.com it gets redirected to https://www.domain.com

In general this is fine, but we have an alias domain for the server, domain2.com, which should keep its domain name (ie not add https//www.), but some part of the config is re-mapping this to https://www.domain2.com

I have checked httpd.conf and the .htaccess in the web app directory, but there dont seem to be any Rewrite or Redirect commands doing this. I have also checked the various include files cpanel/EasyApache uses...

domain2.com is configured as a ServerAlias for the main site.

UPDATE: The main site is written with CakePHP - I can see its doing the "if not SSL, redirect to https", but still tracking down where the "www." is coming from for the other domain.

UPDATE2: There was another .htaccess below the app/webroot directory which was doing a redirect of non-www url's to the www. version.

Redirection could appear in page code, proxy/firewall/checkpoint of any is used, hosts file or DNS server where your domain.com is servered.
