title: Which HTTP header is implemented when server sends same HTTP header multiple times with different values?
body: <p>I came across this one website made in PHP. <code>access-control-allow-origin</code> header is repeated thrice.
  I want to know how is this response handled. Does the latter one hold more precedence than previous one or is it the other way around ? Or both hold equal significance ?</p>
