Bitnami & CodeIgniter

Hello.

I am trying out bitnami with codeigniter but cannot seem to access the url like I did with normal wamp.

I have bitnami wamp stack

But when I type in http://localhost/codeigniter nothing shows up

The requested URL /codeigniter was not found on this server.

Not sure why?

There's only one rule - please don't tell anyone to go and read the manual.  Sometimes the manual just SUCKS!
