I saw that a sofware vendor had used a scheme like this in order for the user to download a file, but that the URL was good for only one time http://www.domain.com/RaNdOmNuMbEr/filename.exe I'm currently implementing a PayPal/file download solution, and I'd like to be able to do something like this. Other than creating a new directory, copying the file over, downloading it then deleting the file, then directory per transaction, can someone suggest how I might do this? The idea is to have be able to hide the true location of a file so that the user doesn't start distributing the URL among all of their friends. It's just a simple security measure. Suggestions, anyone? Frank Marion lists at frankmarion.com Keep the signal high.
