Re: Re: Enabling HTTP_REFERER

Check out http://www.it.ca/software/noleech-light It can still be circumvented by a sophisticated leech, since the REFERER field is supplied by the client, but I've got another one I wrote which gets used in conjunction with another script to dynamically build references to files that expire after a period of time, so that if someone tries to load a file more than a few minutes after loading the page that points to it, the download will fail. I'm not distributing that one publically, but it can be available privately for a fee. p On Tue, Mar 11, 2003 at 03:29:39PM -0500, Stephen wrote: > > I think that solves all my problems then.
