More specifically, if the OP's page is

http://example.com/mypage.php

then he can code

<meta http-equiv="refresh" content="5; url=http://example.com/mypage.php?refreshed=1" />

and the php can then determine whether the meta refresh invoked the page or
not, by testing if it passed the "refreshed" option in the GET.

Note that this does not help distinguish initial page loads from page loads
initiated by the browser's "Refresh" option (^R or equivalent).
