HTTP: Non-Destructive Cache Timing Browser History Disclosure
This signature detects attempts to exploit a known flaw in multiple browsers. An attacker can send a specially-crafted webpage which can deduce the contents of a browser history based on the timing of responses. A successful attack could result in disclosure of a user's browser history to a third party attacker.
