Abstract: Embodiments of the present disclosure disclose a method and apparatus for updating a digital certificate. A specific embodiment of the method includes: receiving digital certificate data, the digital certificate data including a number of times of forwarding and a first forwarding moment; determining whether the following conditions are satisfied: the number of times of the forwarding being less than a preset threshold, or a time length between a current moment and the first forwarding moment being less than a preset time length; and increasing, in response to determining at least one of the conditions being satisfied, the number of times of the forwarding by a preset number, and forwarding the digital certificate data to another proxy server.

Abstract: Embodiments of the present disclosure relate to a method and apparatus for controlling traffic. A method may include: acquiring node identifiers of a plurality of traffic control nodes in a distributed system and a resource identifier of at least one kind of resource controlled by the distributed system; determining, according to the identifiers and at least one resource identifier, at least one traffic control node for controlling the at least one kind of resource in the distributed system being a resource control node; acquiring a configuration quota of the at least one kind of resource; and sending at least one configuration quota to a resource control node controlling a corresponding resource, for the resource control node to determine control quotas for the traffic control nodes in the distributed system.

Abstract: A target data obtaining method and an apparatus provided by embodiments of the present application relate to the technical field of cloud computing. A specific implementation is that: when a cloud server receives a structured query language SQL query statement, which is sent by a client and used to indicate target data that needs to be obtained, the cloud server does not directly issue all data to the client, but first generates an abstract structured syntax tree corresponding to the SQL query statement; and screens all stored data according to the abstract structured syntax tree to obtain the target data; and then sends the target data to the client. Compared with the prior art, in which all data are issued to client, the amount of issued data is effectively reduced, thereby reducing network resources consumed by the cloud server.

Abstract: Embodiments of the present disclosure disclose a method and apparatus for processing a request. A specific embodiment of the method includes: receiving a request; determining a type of the request or an object name indicated by the request; acquiring, after determining that a current time is after a validity deadline of locally stored first request control information, the number of control servers in a preset control server set; determining, from the control server set, a target control server based on the acquired number and any one of: the type of the request, the object name indicated by the request; and forwarding the request to the target control server.
