You have configured the logging in your ICM or WDP:
icm/HTTP/logging_0 = PREFIX=/, LOGFILE=/usr/sap/<SID>/<INSTANCE>/access_logs/$(SAPSYSTEMNAME)_$(INSTANCE_NAME)_access_log-%y-%m-%d.log, MAXSIZEKB=1000000, SWITCHTF=day, LOGFORMAT=%t;;;%H;;;%S;;;%a;;;%r0;;;%j;;;%L;;;%s;;;%b;;;%w1;;;%w2;;;
In the ICM log (/usr/sap/<SID>/<INSTANCE>/access_logs/$(SAPSYSTEMNAME)_$(INSTANCE_NAME)_access_log-%y-%m-%d.log) you find entries like the following:
[03/Mar/2017:11:03:52 +0100];;;<localhost>;;;44320;;;<IP address of the remote host>;;;GET /lms/contentCache/test/data/1002/100004/resources/Fundamentals_EN.flv HTTP/1.1;;;HTTPS;;;136;;;200;;;53928391;;;<SID>;;;J2EE123456720;;;
The problem is with the 2 highlighted fields <SID> and J2EE123456720. <SID> is written by sub-parameter %w1 and J2EE123456720 is written by sub-parameter %w2, which are indeed the host and the instance to which the request was forwarded by Web Dispatcher or ICM.
But the request is never forwarded to that system/instance.
