Does NeoLoad discard/cache/load the files it receives on each request? My understanding is that the AMF Module needs the SWF files only during the Recording phase.
The Adobe swf files are downloaded and executed by the browser so it can render the Flash interface.
During a recording or a load test, NeoLoad will still download this files depending on your cache policy (new user or returning user).
Now, the AMF module does not need them to deserialize or serialize the requests/responses. So it don't really need them during the recording or the replaying.
Let me know if i did not completely answer your question.
