Although my current home page is mydomain/index.php I've still got a lot of old back links to mydomain/index.htm out in the world wide web. These generate 404's which I'd like to avoid. Putting a 301 redirect in my htaccess file screws up my subdomains because they still use index.htm. What is the best way of dealing with this situation? Should I create a dummy index.htm with a simple redirect in it, or is there a better way?
