摘要: Business applications running on a content delivery network (CDN) having distributed application framework can create, access and modify state for each client. Over time, single client may desire to given different CDN edge servers within the same region even across regions. Each need latest “state” of if was last modified by an server. A difficulty arises when process or machine that dies is temporarily permanently unavailable. The present invention provides techniques migrating session data in manner transparent user. thus instance executing server, including nearby (in-region) remote (out-of-region)
