In Chrome dev tools, on Network tab, loading HTML page of normal website (e.g. StackOverflow) at first time looks like this:
... if I continue browsing this website, the "Connecting" time is not present anymore, and request to HTML file looks like this:
But on a website that I'm working on, the "Connecting" time is present on each page load:
In Chrome dev tools documentation "Connecting" status is explained as: "Time it took to establish a connection, including TCP handshakes/retries, DNS lookup, and time connecting to a proxy or negotiating a secure-socket layer (SSL)."
I'm using apache and sending request to simple static file. Do you know what can cause this and what might be wrong in config of server?
