help with mod_rewrite

[eluser]dexter21[/eluser]
Hi, i've a virtual directory in a server:

http://date1.server1.com
localdir :/usr/dates1
codeigniter dir :/usr/dates1/codeig1

i've uploaded ci and config the config. file with the base_url

if i launch http://date1.server1.com/codeig1/ it load the default view that i've write in the routes files, but if i type http://date1.server1.com/codeig1/test.php i get and error that doesnt exist file.

i have a test.php controler that load the view test.php . so i think there is a problem with the mod_rewrite


any help plz?
