Connection between wowza and web page player is not getting disconnected even after closing the web tab.

Hi,

We are using HLS for viewing livestream in web browser and we are counting viewers that how many are watching livestream every 30 secs but we ended with issue that even after closing web tab of web player at viewer the connection between wowza and web browser is not disconnected for longtime(approximately for 5 to 10 mins). Is there any solution to fix it??
