It's more efficient to write: static int yahoo_hostname_handler(request_rec *r) { if (r->method_number == M_GET) { r->content_type = " text/plain"; … ... } return HTTP_NOT_IMPLEMENTED; } instead of checking that r->method_number != M_GET for each and every request (unless compiler optimizations render them equivalent) I find it interesting that he writes in the summary (slide 55): “Every CPU cycle counts” but then shows code like that on slide 41.
