php - what kind of download counter big websites companies have?

I am developing in php and trying to implement a download counter to count the times that users downloaded my application.. I also read the following topics:

Best way to implement a download counter?

Best way to count file downloads on a website

and found nothing useful enough..

What I would like to ask is: what kind of download counter the big companies implement? is it when the user cancels the download doesn't count?

Is it even possible - to count file downloads, and remove 1 from the count if the user canceled the download?

I already have a script that works great - but only when开发者_运维问答 the file is 1MB or upper, when its less than a 1MB and a user cancels the download - the download still counts..

Thanks in advanced, Din.

Nobody cares about canceled downloads (and in fact, bigger number looks cooler for management & users).

It is just counted via dummy redirect/logs analyzing.

No rocket science.
