Classes in 'welcome' handler and URI structure

[eluser]jairoh_[/eluser]
that's the purpose of routes sir.
if you won't use routing, you will use http://mysite.com/welcome/privacy because that's how it works when calling a controller function.
base_url/controllername/controllerfunction or base_url/index.php/controllername/controllerfunction and it's not a problem. i use this one.

hope this helps.
