Sending file path to controller

[eluser]Loque[/eluser]
Hi all,

I have done some searching (probably not looking up the right terms) and i really cant find any information on sending filenames, or varialbes containing '/' to controllers. At the moment I would like to use the force download function, and have an individual controller to handle this, so something super basic like;

Code:

function download($s_name,$s_file)
{
    force_download($s_name,$s_file);
}

and say my link to this would be something like;

www.theSite.com/controllerName/download/filename.jpg/file/path/here/is/never/going/to/work/filename.jpg

I cant think of a way of getting around this other than stripping the slashes and then putting them back in, and that just feels wrong - someone please slap with common sense and help me if you have a mo!

Cheers,
Loque
