Is there a problem with my Keep Alive settings?

I am struggling to understand this …

When I run a test for one of my test websites, I am seeing that keep-alive is enabled.

But when I take a look at the connection view,

I see that there are several TCP connections being made for the domain.

I am trying to understand why several TCP connections are being made although keep-alive is enabled.

And what can be done to ensure that only one TCP connection is made?

Thanks!

Browser will open multiple connections even with keep-alive so they can pipeline requests and avoid idle time. To get most of the requests going over a single connection you need to support HTTP/2 (which requires HTTPS)
