I am using the Zend Framework to test some sample scripts. I just realised that in order to get to my view page my URLs need to look like this: 'http://app_home/index.php/user/gohome'

Why does the index.php have to be part of that URL? If i take it out then i get an Object not found error. How can i make my URLs be 'http://app_home/user/gohome'? Where user and gohome map to both my controller and action respectively. Why does index.php always needs to be there???
