System and method for prefetching uncacheable embedded objects

摘要

A system and method for prefetching one or more embedded objects marked uncacheable using a buffer on a prefetch cache to temporarily store the uncacheable object. The buffer is allocated to a socket that is established between the prefetch cache and a server subsequent to the establishment of an initial connection. A prefetch caching process retrieves one or more embedded objects from the server using the socket based on the preconfigured set of rules. The prefetch caching process determines whether the embedded object is uncacheable, and if so loads the object into the buffer. The prefetch caching process waits a predetermined time period for client request for the object. If the request is received prior to expiration of the time period, the prefetch caching process sends the object to the client. Otherwise, the process “flushes” the buffer, thereby discarding the object, and then closes the socket.
