METHOD AND APPARATUS FOR DYNAMIC DATA FLOW CONTROL USING PRIORITIZATION OF DATA REQUESTS

摘要

A data center determines whether requested content is available at the data center. The content is available when the content is both present at the data center and current. When the requested content is available at the data center, the data center returns the requested content to the browser. When the requested content is locally unavailable at the data center, the requested content is retrieved from an origin server. When retrieval of the content is delayed, the request is prioritized and placed in a queue for handling by the origin server based on the priority of the request. A status page may be communicated to the browser to inform a user of the delay and provide alternate content and status information related to the request determined as a function of the request or the current state of the origin server.

主权项

1. A method for flow controlling data requests in a computer network, comprising:
transmitting an initial request message to a flow controlled server, the initial request message being associated with a data, request from a requesting browser and requesting permission to retrieve data from a protected source, the initial request message including a request identifier associated with the data request; receiving an initial response message from the flow controlled server, the initial response message indicating whether permission is granted to send the data request to the protected source, the initial response message upon permission being granted including a pause value indicating a length of time before a status page is to be sent to the browser, a refresh value indicating a length of time before the browser is to send the request identifier associated with the data request, and a uniform resource locator of the status page; sending the data request to the protected source through the flow controlled server.
