Detect Parallel Download / Download Status (In Progress / Cancelled / Completed)

[akshay]

Hello.

 

How do I detect parallel downloads for an IP ($_SERVER['REMOTE_ADDR']) from my website?

 

(If Download in progress / completed / cancelled)

 

Example, to reduce server load, I want to detect if a user is already downloading, he should see:

"Sorry! Parrallel Downloading not allowed"..

 

I'm not asking for the script. But a hint where I can find info, or the logic behind it..

 

Thank you!
