How to keep url clean on calling $this->index()

[eluser]vercoutere[/eluser]
Hey, thanks for the quick reply!

Using that redirect still has the /index.php/main popping up in the URL bar. Though I could use a redirect to the base_url in this case, but the real issue when using redirect is that the set_value() function for the form fields doesn't get anything from the post anymore, so the values that were filled in by the user don't get remembered.

(I hope I'm making myself clear here, English isn't my first language :-))
