multi-file flash pieces

[eluser]coffeeandcode[/eluser]
Hi all, I use global constants for my WEBROOT and assets - IMG, CSS, etc. I also use one for flash - SWF. This works okay for single file flash pieces, but I have one multi-file piece that doesn't work. I checked out the headers while I was trying to use it and, instead of looking for the other files in the SWF directory, it's looking in the "current" directory. ie, if the url to view the flash piece is http://www.example.com/flash it's looking for the other files in http://www.example.com/flash/files. This was written and used before we were using a framework, when the url structure matched the directory structure. With CI it's not as simple, and I'm not sure how to do this. The fact that I don't know very much about flash doesn't help. Any suggestions?

Thanks!
