Hi Andy - Why would you want to do this? From a usability point of view, it isn't always pleasant to have to sit in front of a computer to listen to files; I would much prefer to listen to them on another device. Indeed, I find that I almost never make use of streams that cannot be downloaded, so it is likely to repel some of your visitors. Of course, it depends on the actual content: for instance, books must never be streamed (what if you wanted to stop halfway and then resume a few days later?), whereas music seems more workable this way, as does live content. -Graham. _____ From: programmingblind-bounce@xxxxxxxxxxxxx [mailto:programmingblind-bounce@xxxxxxxxxxxxx] On Behalf Of Andy B Sent: October 30, 2007 11:07 AM To: programmingblind@xxxxxxxxxxxxx Subject: protecting streaming mp3 files with asp.net? Hi... I have to stream mp3 files from an asp.net 2.0 website. I am trying to figure out how you can let any visiter to the site play them but not download them. Most of the examples out there show how in flash, but is there another way?
