void CBrCtlSampleAppSpecialLoadObserver::NetworkConnectionNeededL (  TInt *  ,
TInt *  ,
TBool *  ,
TApBearerType * 
) 
 

Request to create a network connection.

Since:
2.8
Parameters:
aConnectionPtr A pointer to the new connection. If NULL, the proxy filter will automatically create a network connection
aSockSvrHandle A handle to the socket server.
aNewConn A flag if a new connection was created. If the connection is not new, proxy filter optimization will not read the proxy again from CommsBd
aBearerType The bearer type of the new connection
Returns:
void

Request the host applicaion to handle non-http request.

Since:
2.8
Parameters:
aTypeArray Array of download parameter types. These types indicates the type of data contained within the DesArray
aDesArray Array of values associated with the types in the type array.
Returns:
ETrue, If the request is handled by the host application. EFalse if not
