Still quite confusing because the "last" portion goes on to say "after
which searches for corresponding URI and location". As the "break"
part does not say anything, it implies that "after which DOES NOT
search for corresponding URI OR location". I.E. It implies what
agentzh wrote.

Perhaps needs some clarification about it being appropriate at server
level (If I understand you --- totally confused lol).
