| | It is the DA responsibility to validate the SID. In most cases, DA should keep a list of SID for faster handling on user requests, avoiding to pass back verification query to the AOS.
However, if the DA is not responsible for initiate the session, the first SID arrive to DA must be verified before proceed. Some DA handle user browser request directly. In order for AOS to redirect SID to a DA, AOS must know the entry point of the DA, in this case, is the DA's URL.
DA URL may looks something as such:-
http://daserver.dadomain.com/dascript.pl?sid=SIDxxxxxxxxxx http://192.168.1.5/da.cgi?sid=SIDxxxxxxxxxx AOS instructs the user browser to query DA with the predefined DA URL, by specifying the user SID as URL parameter. The developer responsible for a DA must let the AOS admin know the Entry Point of the DA (which is only an URL) so that AOS may redirect the user correctly. | |
