How does the Internet Communication Manager (ICM) "know" which browser-based requests are intended for the AS ABAP part and which requests are for the AS Java part?

Consider an SAP system that is based on AS ABAP + AS Java (for example an SAP Exchange Infrastructure system).

How does the Internet Communication Manager (ICM) "know" which browser-based requests are intended for the AS ABAP part and which requests are for the AS Java part?
A . For systems based on AS ABAP + AS Java, the ICM can only distribute incoming request to the AS ABAP part. Requests to the AS Java part must be sent to the Java Dispatcher directly.
B . By analyzing the URL prefix of the corresponding request and by comparing this request with the entries of the URL prefix table. Entries in the prefix table indicate requests for the AS ABAP part.
C . By forwarding this request both to the dispatcher of the AS ABAP part and to the dispatcher of the AS Java part of the instance. Only the "correct" dispatcher will execute this request.
D . By evaluation of a session cookie from the browser.
