   The Key word in here is = Application. The fact that it is an HTTP Based application is irrelevant.
   All applications operate at Layer 7 of the OSI model.

   OSI LAYERS:
   Layer 7–Application layer.
   Layer 6–Presentation layer.
   Layer 5–Session layer.
   Layer 4–Transport layer.
   Layer 3–Network layer.
   Layer 2–Data Link layer.
   Layer 1–Physical layer.

   Explanation:
   An application-level gateway firewall filters traffic based on user access, group membership, the application or service used, or even the type of resources being transmitted.
   This type of firewall operates at the Application layer (Layer 7) of the OSI model.

   A.Protocol filter:
   A Protocol Filter feature is used to block unwanted traffic from your network. They are used in Firewalls and work at Layer 3–Network layer.

   B.Load balancer
   This is to balance the load and will do absolutely nothing to aliviate the issue at hand

   C. NIDS
   Network Intrusion Detection Systems (NIDS). This operates at a NETWORK level, and not just an APPLICATION level

   So “D. Layer 7 firewall” is the BEST suited
