Abstract
A first compute server of a distributed cloud computing network that includes multiple compute servers receives an API request that is directed to an API endpoint. The first compute server determines an identifier that uniquely identifies a session that is associated with the API request. Based on the determined identifier, the first compute server determines which of the compute servers of the distributed cloud computing network is responsible for storing information about previous API operations associated with the determined identifier. The first compute server transmits an API sequence request to the determined compute server. In response, the first compute server receives information that specifies a time-ordered sequence of API operations associated with the determined identifier most recently observed. The first compute server may enforce a rule based at least on a sequence of at least two of the latest API operations.
