Subject RE: Problems downloading files. How to identify the CANCEL butto n?
Date Sun, 12 Jul 2009 02:58:21 GMT
Andre came up with a good reason and here is mine:

I work for the brazilian government that wants to keep track of people who
download certain specific files. It also wants to send emails to the ones
that at least started the download procces of these files. So, for this
reason, there is no interest at all to send emails for those that canceled
the download process.

I am looking forward for a solution because the way my code is now is wrong.
It is logging everybody no matter which button they pressed (open, save or
cancel).

Once more, any suggestion is more than welcome.

Siomara

A usual example is when the customer is paying for some downloaded 
document.  At the server side, you would want an absolute, 
no-complaints-possible, trace that the download did occur succesfully.

Something you can wiggle under the customer's nose when they complain 
about the bill.

All the more reason to have some active component at the client side, 
acknowledging the download back to the server, with some unique 
timestamp, id, etc..
