Apache2, php, web service POST request problem

Imam napravo, ki pošilja podatke na strežnik po http POST requestu. Napisati moram testni strežnik za shranjevanje podatkov. Postavil sem WAMP, problem pa je, ker se na programiranje spletnih servisov ne spoznam ravno najbolje. Workflow je sledeč:
1. Naprava se registrira na strežnik. Ta del sem rešil tako, da sem v mapi www/provision naredil activate.php datoteko s funkcijo, ki vrne unique id. Za test sem uporabil fiksen string, ki sem ga vzel iz dokumentacije: f75fab38b23b56e767f178677c5df3a4eed5120f. Ta del mi dela. Naprava je prejela ID. Besedilo iz dokumentacije:
* Sent to Server*
Content-Type: application/x-www-form-urlencoded; charset=utf-8
Content-Length: 42
HTTP POST "/provision/activate"
vendor=novus&model=logbox3gstd&sn=00001232

* Received from the server *

2. Ko je naprava registrirana na strežniku, periodično pošilja POST request na strežnik. Tu se mi ustavi. Mislil sem narediti podobno, kot pod točko 1, samo ne vem, kaj pomeni : v urlju. Windows pač ne dovoli : v imenu mape. Dokumentacija:

Vsakršna pomoč je dobrodošla.

Nekdo je bil mal prevec clever pa je dal : v URL, to ni nic takega. Je pa annoying ce si hotel kar z direktoriji delat. Sej si napisal rewrite rule, torej je zadeva resena?
