keepalive type http head non-persistent

[kedwards]

Ok,in the context of this, what is the difference between a "Keepalive http head persistent", and "non-persistent"? What do they mean by "persistence" in this context???

[Gilles Dufour]

the same as for a browser.

A persistent connection means 1 connection for all the http request.

Non-persistent means 1 connection per http request.

So, in the case of http keepalive, if using persistent the CSS only open 1 connection and simply send a new HTTP request every frequency-interval.

Gilles.

Thanks for rating this answer.

So, we then assume that a keepalive http-persistent is more CPU intensive because of the CSS keeping the Tcp session active and keepking track of it? If that's the answer, then I get it...
