AVR sometimes detects the incorrect BIG-IP module that created a response to an HTTP transaction.
1. AVR report an incorrect module. 2. Application DoS is using this information for its decisions, and thus can choose a mitigation action that is different from the desired one.
Using AVR HTTP profile or Application DoS, and having a transaction that was responded to by a BIG-IP modules, such as DoS, Cache, iRules, and so on.
None.
The detection of the internal module is done correctly, so that the correct mitigation action is chosen.
