Abstract: Implementations of the systems and methods discussed herein provide for distributed HTTP proxy services with synchronization of per-server or per-tenant resource allocation counters amongst the proxy devices, allowing devices to quickly identify denial of service attacks or other malicious or erroneous behavior. In some implementations, a database server may receive resource consumption notifications from each of a plurality of proxy devices and may aggregate the notifications or increment a counter on a per-server or per-tenant basis, and provide updated counter values to proxy devices via callbacks. Each proxy device may check the counter value before utilizing resources, and may disable or block proxy processing responsive to the counter exceeding a threshold.
