Use
This call aborts a current request if there is one associated with the session identifier. In the event of no request being associated with the identifier, an error is generated. The purpose of this SWI call is to provide the client with a way of enforcing the termination of a request. It is not called by the client just because all the data associated with the request has finished being transferred, although it may do that if it so chooses. The URL_Stop call will be made automatically by the URL module when the session is deregistered by the client using SWI URL_Deregister.
When this SWI is called, the URL module invokes the Protocol_Stop SWI for the protocol module concerned with the request.
