Abstract
Exemplary methods, apparatuses, and systems include a proxy intercepting, from a client, a plurality of requests addressed to a first server. The proxy adds an entry for each of the plurality of requests to a data structure. Each entry includes data from one of the plurality of requests. The proxy forwards each of the plurality of requests to the first server. In response to detecting the first server was unavailable or otherwise failed, the proxy reconnects to the first server when the first server recovers or connects to a second server serving as a backup for the first server. The proxy transmits to the first or second server one or more commands using the entries of the data structure to restore state information for the client.
