Extracts the name of the Network Operator from an HTTP request.
This feature searches the request URL parameters for a name-value pair with name identified in the HttpParameterForHttpDetermineNetworkOperator field of the SentinelPlatformConfiguration.
The feature then attempts to map the discovered value to a network operator name by looking it up in the SentinelHttpParameterToNetworkOperatorProfileTable.
If the parameter is not found in the URL or there is no mapping available in the SentinelHttpParameterToNetworkOperatorProfileTable, a default network operator is used, as configured in the DefaultNetworkOperator field of the SentinelPlatformConfiguration.
For example, consider an HTTP trigger containing the following URL:
HttpDetermineNetworkOperator will query the name of the HttpParameterForHttpDetermineNetworkOperator in the SentinelConfigurationTable by selection key. In this case it returns “calledstationid”. The corresponding parameter value 00102 is then extracted from the URL, and the profile of the same name is retrieved from the HttpParameterToNetworkOperatorProfileTable. From this profile, the NetworkOperator is retrieved and stored in session state.
