Several classes are involved in handling an incoming request. When a Web Connection part is instantiated as part of a request, an AbtWsiTransaction object is created and associated with the part. The AbtWsiTransaction object contains references to two other objects, an AbtWsiRequest object which models the request data, and an AbtWsiResponse object which models the response data.

These classes provide methods you can use to access various data associated with the request. Following is a description of these classes and their methods.
