SMART REDIRECTION AND LOOP DETECTION MECHANISM FOR LIVE UPGRADE LARGE-SCALE WEB CLUSTERS

摘要

Handling requests for resources of a web based service. A method includes receiving a request from an external client for a resource. The method further includes determining that the resource is not available in a first version of a web based service. The method further includes providing routing information to a second version of the web based service. The routing information is readable by the second version of the web based service to allow the second version of the web based service to handle the request as a request from the first version and not simply a brand new request from the external client.
