TCustomAdapterDispatcher calls GetDispatchParams internally to obtain information about the adapter to which a request is directed. GetDispatchParams creates a new TAdapterDispatchParams object, which parses the current request to determine the adapter to which it is directed. 

Request is the current http request object. 

GetDispatchParams returns the new TAdapterDispatchParams object, whose properties have been filled out to reflect the information in the current request. It is the caller's responsibility to free this object.
