Unfortunately, there is no real way to prevent a user from saving a web page. One way or another he/she will be able to save the information offline. That is, assuming, of course that it's in html form. If you display confidential information inside an applet, activex, or plugin, then the designer has more control over security.



For the issue of managing user *access* to a protected page, the best and most reliable way is to either use your webserver's built in security mechanism (like challenge-response authentication) or password protect the page with a server-side login mechanism linked to your own user database (which is what most sites do today). You can even use both.



The details of either one of these solutions is dependent on your architecture and software. You can post any relevant questions in the proper forums for each :)



Hope that helps,
