I am getting an problem with Railo 3.1. running under Apache on Home windows Server 2003.

When likely to http://www.domain.com it defaults to index.cfm.

When likely to http://domain.com it does not find index.cfm. http://domain.com/index.cfm works fine.

Anybody know where I'm able to configure this?

Appears like Apache virtual host misconfiguration, not Railo. Re-check DirectoryIndex setting for domain.com site config (in sites-available), it will contain index.cfm on to begin with.
