.htaccess and 404s on every request

[eluser]mipa[/eluser]
Hi,

I've used the .htaccess file available on the Wiki to implement "pretty URLs" for our CI project.

Today, after running our Apache logs through a log analyzer, it seems that Apache logs a 404 for *every* CodeIgniter request. Is this because the .htaccess checks for the existence of the file in this line?

Code:

RewriteCond %{REQUEST_FILENAME} !-f

Or is there some other reason? I'm just curious if this is correct, or if we have some configuration error somewhere.

Cheers,

Mipa
