    摘要： The invention is a method and apparatus for maintaining session affinity within a server farm when requests sharing a session ID switch between server groups or between server clones in a single server group. In accordance with the invention, client requests include a list of clone identification codes, each code uniquely identifying a clone within a server group for handling the request. The clone identification code may be appended to a session identification code. For each different server that handles a request in a session, a new clone identification code is appended without deleting or overwriting any previously appended clone identification codes. When a request is received, the list of clone identification codes associated with the request is parsed in a predetermined order to search for the first clone identification code that matches one of the clone identification codes of a server in the appropriate server group. If a match is detected, the request is dispatched to that clone. If no match is found, the request is dispatched to a server clone in the server group using any reasonable Work Load Management (WLM) mechanism and then the clone identification code of the selected clone is added to the list.

    摘要： The invention is a method and apparatus for invalidating session data stored in a database. In accordance with the invention, http sessions stored in the database are allowed to remain in the database without real time testing for session time out. Instead, invalid (or timed out) sessions remain in the database until a specified time. At that specified time, all http sessions are invalidated without actually testing them for time out. Alternately, each session can be individually tested for time out and only those sessions which have actually timed out are removed from the database or otherwise invalidated.

    摘要： A method, system, and computer program product to transparently dispatch requests to a remote resource using a remote request dispatcher (RRD) in a managed multiple application server environment. The method includes executing a local resource on a local Web module on a local application server. The local resource contains a reference to a remote resource on a remote Web module on a remote application server. The method also includes building an RRD request object on the local application server, and sending the RRD request object to the remote application server. Upon receipt, the method further includes generating a request on the remote application server to an internal controller servlet to perform an include operation on the remote resource, intercepting the request to the internal controller servlet on the remote application server, wrapping the request to the servlet with information received in the RRD request object, and building an RRD response object on the remote application.

    摘要： An improved method, apparatus, and computer instructions for managing a set of servers. Responsive to an indication that an alteration of applications on the set of servers providing a service is to occur, a first group of servers and a second group of servers are created from the set of servers. The first group is designated for handling ongoing sessions with unaltered applications. The applications in the second group are altered. A server from the first group is transitioned to the second group as ongoing sessions handled in the first group decrease in number to form a transitioned server, wherein the alteration of the applications are performed without interrupting the service.

    摘要： Embodiments of the present invention address deficiencies of the art in respect to edgified content delivery and provide a method, system and computer program product for dispatching of request fragments from a response aggregating surrogate. In one embodiment, an edgified content distribution data processing system can include an origin server configured to server markup specified pages formed from dynamically arranged fragments and a surrogate server communicatively linked to the origin server over a computer communications network and acting as a surrogate at an edge of the network on behalf of the origin server. A dependency engine can be coupled to the surrogate server and can include program code enabled to group the fragments according to interdependencies among the fragments and to load fragment groups in sequence to satisfy the interdependencies.
