Dear Jerry,
You fully understand the situation im in right now... Mayb i will
elaborate more on this.
My application is to correspond with a mobile provider gateway
using HTTP calls. And meta refresh is not allowed.
Initially i din have to do any redirect as the process is actually
very simple. Once a mobile user register the service with their mobile
phone, the provider will call/send in the parameters to my
page(assuming receive.php). And upon receiving the parameters, i need
to echo "-1"; to the provider so a standard message will be sent out
to the registrant. The -1 is a requirement from my provider. So they
only recognized this. (according to their API). The reason why i have
to redirect is because some registrant might not be providing enough
information, so i did a strlen($sms) on the sms receive to see how
many characters is there and therefore determine whehter the info is
complete or not... So there are 2 situations, complete info and
incomplete info. Both i will reply -1 for them to receive the standard
sms but only those with incomplete info will receive a customized msg
from my side. That's the thing. If i put on the same page, those with
incomplete msg cant receive anything ask the provider only recognized
-1 for the registration process.... Thanx.
