+ On some devices we see that doing a second preconnect on HTTP/1.1 is a significant page load time improvement.
+ This is due to the fact that most page loads on HTTP/1.1 will open several connections, and having two
+ preconnected connections instead of one, will speed up page load time. This patch implements this by starting
+ a second preconnect after the first has finished. It is important to wait until the first preconnect has
+ finished, otherwise the second preconnect will go to waste, since the underlying network layer does not yet
+ know if this is HTTP/1.1 or not. Since we do not see page load time improvement on iOS with this behavior,
+ it is currently only enabled for macOS. The next step is to investigate why it does not seem to be a page
+ load time improvement on iOS. We probably need to make sure the main resource load has started before we
+ start the second preconect. This will avoid that the second preconnect returns immediately.
