Fixes #212
Previously only
$_SERVER
values prefixed withHTTP_
(i.e. HTTP headers) were returned; I updated this as in some cases (e.g. with nginx configuration) theX-Request-Start
header value may be set directly into$_SERVER
, rather than being prefixed (such as how Apache does by default). This makes the header checking more flexible and less fussy to configure.
