suppose when user click on link or button for downloading file in asp.net then download start.
so i just want to know how to detect that the file as been downloaded in client machine.
is it possible to track from server side code. because i want to develop a file download section
from where user at a time can download only single file. so in this case when file download start
i will just capture client ip and store it in session and so when user click on another link to download another file
at the same when another file is downloading so in this situation i will check file is downloading from this ip and if yes
then i will reject user request and tell him that sorry already a file is downloading so try after when this download will
be over. when file download will be over then i will clear that session and in this way my purpose will be solved and
restric user to downlolad multiple file.this type of things is used in rapidshare, ...
