you mean the output of the aspx page? the html? you can't. html is sent to the browser and the browser will cache the html for a period of time. you can control the caching, but it still caches.
for copy write material there are 2 common approaches you see on the web.
1. a copy write watermark. this is placed on top of images so if the image is "copied" or "linked to" you your watermark will appear on it.
2. place a copy write statement on the page. usually there is one static page with the copy write notice. each page contains a copy write symbol/year/owner in the footer with a link to the details of the copy write notice.
as a general rule though. the internet is one giant Xerox machine where any and all information *can* be taken. after all the net is about collaboration. If you really cannot have the material stolen/reposted/scrapped/etc. then simply do not put it on the web.
