Yes.

Yes, because we start fetching images while the page is still loading.

Yes, this is to prevent that we accidentaly POST the form twice. If we were to 
reuse the same connection it can happen that at that very moment that we send 
the data, the server decides to drop the connection. The HTTP spec allows 
that but in such situation we will not know if either a) the server never got 
our POST request and we would need to retry or b) the server got the request 
but a network error occured.

It's an implementation matter although HTTP headers play a role as well, since 
the remote server can explicitly request the closing of the connection.
