Hi Helix, Thanks for the reply. I will look into it.
I'm working with lighttpd to host large video files. It seems to be working but i still have to make some more checks. My "problem" is that the url pointing to the file is viewable in the source code leading to the possibility of a third party linkining to the file. By using the secdownload module, links expire after a certain amount of time, thus discouraging direct linking.
