Hi, With 'cache-control:no-cache', the downloading is disabled for users using IE but it doesn't work for users using netscape. A ftp pop-up window comes out once user clicking on a file for opening. Is there any way to disable netscape to download the file with using PHP script? Any help is much appreciated. zhq

Dear All, My website is using MySql database and php. I intend to block users from downloading and saving pdf file while viewing it online. From the php forum, I know that saving file could be disabled if javascript is used to construct the page. Anyone has such javascript? Any help is much appreciated. zhq

Dear All, Sorry I am not quite clear about this becasue I am new to all the topic. Using "header('Cache-Control: no-cache')", the downloading to the temp directory can be blockbed. For blocking user to use the 'save as' function to save a PDF file, the java script has to be used. Am I right? Instead of using Java script, can PHP script work for this? I need a clear drection so that I know how to start my work. Thanks. zhq
