Method and apparatus for causing a delay in processing requests for internet resources received from client devices

摘要

A method and apparatus for causing a delay in processing requests for Internet resources received from client devices is described. A server receives from a client device a request for a resource. The server transmits a response to the first client device indicating that access to the resource is temporarily denied. The response includes a cryptographic token associated with the first request and a predetermined period of time during which the first client device is to wait prior to transmitting another request to access the resource. The server receives a second request for the resource, upon determining that the second request includes a valid cryptographic token, the server causes the second request to be processed. The server receives a third request for the resource, and upon determining that the third request does not include a valid cryptographic token, the server blocks the third request.

1. A method of causing a delay in processing requests for resources received from client devices, the method comprising:
receiving, from a first client device, a first request for a resource; transmitting a first response to the first client device indicating that access to the resource is temporarily denied, wherein the first response includes a cryptographic token associated with the first request and a predetermined period of time during which the first client device is to wait prior to transmitting another request to access the resource; receiving from the first client device a second request for the resource; in response to determining that the second request includes a valid cryptographic token, causing the second request to be processed; receiving from a second client device a third request for the resource; and in response to determining that the third request does not include the valid cryptographic token, blocking the third request.
