    If you wish to prevent the pdf from being cached in the client computer,
    then put all your pdf's in a directory and then in the "Properties" of that
    directory (inside "Internet Information Services") go to the "HTTP Headers"
    tab and add the "Expires: -1" header.

    I believe that will do.

    Subject: Prevent caching of pdf files

    Currently on a secure Internet application we use the "Cache-Control: No
    Cache" header to prevent information from caching on client machines. We
    would like to begin to provide pdf files via our application; however,
    there is a known issue with accessing pdf files with IE 6.0 sp1 when the
    no-cache header is used. (Please refer to
    http://support.microsoft.com/default.aspx?scid=kb;en-us;812935
    for details.) As we have no control over the client machines accessing
    our application, is there another way to prevent pdf files from being
    automatically stored on the clients without using the no-cache header?

    Thanks in advance,
    -Brett
