[SOLVED] URL rewriting with CI

[eluser]Unknown[/eluser]
Hello,

I'm developing a little website to find some POI. So really easy on my home page I have 2 searchfield "Where" and "What"
So If i enter "London" "Restaurants" I send the search field variables to my controller that will work and return me some results.. OK until here..

But I can do for example if I enter an URL like this

http://localhost/London/Restaurant

So here the controller will receive where=London an What=Restaurant ?

Because now I have to make it works I have to do that

http://localhost/index.php/welcome/index...Restaurant

I would like to remove the index.php and the variable name (Where and what). How can I do that? With URL rewriting ? If so How Can I do it with CI ?

Thank you
