Unusual requests initiated by /TSPD directory on f5 firewall

This is normal JavaScript injection used by F5 Adv. WAF to assess a client for the purpose of fingerprinting to determine if it's malicious or legitimate. Fingerprinting comes in two forms: active and passive. Passive fingerprinting doesn't Query the client--it only checks for a list of attributes. Active fingerprinting challenges the client. It can force a client to prove it supports the JavaScript API, execute mathematical challenges, and a range of other tests that verify the client is what it claims to be. Even sophisticated bots cannot fake replies. What you are seeing is the client-side challenge where the browser fingerprinting is occurring. The white page you see is transient and should not cause any performance degradation. The firewall cannot be compromised.
