break; usage

[Jonathan Dance]

Hi,
I was wondering if anyone could clarify what "break;" does - basically, does
it stop all processing, or only rewrite processing? What is its effect on
proxy_pass? Here are two simple contrasting examples:


location / {
  if (!-f $request_filename) {
    proxy_pass http://somewhere;
    break; # does this do anything?
  }
}

# Is that any different from this?

location / {
  if (-f $request_filename) {
    break; # avoid the proxy_pass?
  }
  proxy_pass http://somewhere;
}

Thanks!

JD
