[pmwiki-users] Where does pmwiki.php points to?

[kirpi at kirpi.it]

I would like to see http://www.eva24-7.it/eva/pmwiki.php point to
http://www.eva24-7.it/eva/pmwiki.php?n=Eva.HomePage and not
http://www.eva24-7.it/eva/pmwiki.php?n=Main.HomePage.
I tried an index.php file with
<?php header( 'Location:
http://www.eva24-7.it/eva/pmwiki.php?n=Eva.HomePage' ) ;
in the same directory of pmwiki.php, but I'm always sent to Main.HomePage.

Where do I fail, please?

Thank you
Luigi
