How to enable/disable HTTP Compression function from your control panel

Control Panel V3 > Hostings > Websites
You can enable/disable HTTP Compression function from  your hosting control panel --> Websites --> Find the target site and click "Manage Websites" --> Then turn On or Off button beside HTTP Compression.
 
However if you re-upload your web.config file to your site folder, you'll need to turn On/Off the function again.
