How to enable HTTP persistent connection?
HTTP persistent connection is a performance enhancement feature that reduces latency and allows web pages to load faster.
It uses a mechanism called idle keepalive connections to hold open the TCP connection between the client and the server. This is done by regularly sending HTTP keepalive messages, so when the client needs to conduct another HTTP transaction it will simply use the idle keepalive connection rather than creating a new TCP connection.
To enable HTTP persistent connection, navigate to ‘ Multi CDN’ > ‘General settings’ > ‘Persistent connection’.
On the ‘Persistent connection’ box, click the ‘Settings’ (gear) icon to set the ‘Keepalive time’.
Keepalive time is the duration that the link will remain connected after it becomes idle. It can be set from 1 to 100 seconds, with a default value is 75 seconds.
