[PHP3] Detecting Aborted Downloads... From: Alex MacFarlane (nash <email protected>)
Date: 08/08/99

    I'm attempting to set up a credit-based fileserver-type website. A user
has X bytes of credit in his account and when he downloads a file the
filesize is subtracted from his credits. The feature I'm attempting to
implement is detecting the user either cancelling the download or perhaps
getitng disconnected from his ISP.
    Currently I am serving the files by using the Header() and readfile()
functions (so that the true location of the file is never known to the user-
otherwise he could get the file without 'paying' for it with credits). In
this scenario I cannot use the connection_aborted() function can I? Can I
use the return value of readfile() somehow?
    If I use the EMBED html tag, then I have no control over whether the
download is completed. And I obviously cannot have a simple <a
href="filename"> tag because then the user can get the file without
deducting from his credits.

    Is this even a possibility? Thanks for any pointers...
