I am putting up a website for a client. The problem is that - for some reason - the host that they are on doesn't seem to redirect the URL (say - http://www.abcxyz.com) to http://www.abcxyz.com/index.php. At the moment, I have stuck up a meta refresh, but wouldn't mind a more search engine friendly solution, is there a .htaccess approach or another approach that would correct this error?
