Abstract: An apparatus and method for off-loading application components to edge servers are provided. An application is made edge-aware by defining which components of the application may be run from an edge server, and which components cannot be run from an edge server. When a request is received that is to be processed by an application on an origin server, a determination is made as to whether the application contains edgable components. If so, an edgified version of the application is created. When a request is received that is handled by a component that may be run on the edge server, the request is handled by that component on the edge server. When a request is received that is handled by a component that is not edgable, the request is passed to a proxy agent which then provides the request to a broker agent on the origin server.

Abstract: A method, a system, an apparatus, and a computer program product are presented for a fragment caching methodology. After a message is received at a computing device, a fragment in the message body is cached. Cache ID rules from an origin server accompany a fragment to describe a method for forming a unique cache ID for the fragment such that dynamic content can be cached away from an origin server. A cache ID may be based on a URI and/or query parameters and/or cookies that are associated with a fragment. After user authentication, a cookie containing the user's role may be used in subsequent requests for role-specific fragments and in the cache identifier for role-specific fragments, thereby allowing requests from other users for role-specific fragments to be resolved in the cache when the users have the same role because these users would also have the same cookie.

Abstract: A method, a system, an apparatus, and a computer program product are presented for fragment caching. After a message is received at a computing device that contains a cache management unit, a fragment in the message body of the message is cached. Subsequent requests for the fragment at the cache management unit result in a cache hit. The cache management unit operates equivalently in support of fragment caching operations without regard to whether the computing device acts as a client, a server, or a hub located throughout the network; in other words, the fragment caching technique is uniform throughout a network. Cache ID rules accompany a fragment from an origin server; the cache ID rules describe a method for forming a unique cache ID for the fragment such that dynamic content can be cached away from an origin server.

Abstract: A method, system, and computer program product, by which portions of the session information that page-content is dependent upon are “pushed” to the client from the origin server in a way such that auxiliary servers, e.g. other application servers and edge-servers, have access to the session information and fragment dependancy data to generate auxiliary-server cache-IDs for the custom pages. This enables distribution of the load away from the origin server, allowing better application distribution and scalability through more effective caching.

Abstract: A method, a system, an apparatus, and a computer program product are presented for a fragment caching methodology. Within the request path from a client to a server, a first computing device may attach to a request message a message header that indicates that the first computing device supports fragment processing; a second computing device within the request path processes this request message. When the second computing device receives a response message corresponding to the request message, it can check for a message header directive that indicates that it should cache the response message's fragment only if the response path does not have at least one computing device that supports the processing of fragments; if so, then it forwards the response message without caching its contained fragment.

Abstract: A Fragment Aggregator utilizes an application independent surrogate to dispatch fragments and receive responses between isolated web applications. Clients send web application requests to the surrogate, which forwards the request to an isolated web application. When a web application requires other isolated web applications to execute the request, the web application responds to the request with a deferred response. The deferred response includes request fragments for the other isolated web applications. The Fragment Aggregator dispatches the fragments to the other isolated web applications. After receiving responses from the isolated web applications, the Fragment Aggregator combines the response and sends them to the client.

Abstract: A Fragment Context Preserver has two components, a Fragmented Request Preserver and a Request Context Helper. The Fragmented Request Preserver program runs on a surrogate attached to a client computer and distributed computer environment, and a Request Context Helper runs on each application server on the distributed computer environment. Working together, these two programs ensure that independently dispatched fragments of a request execute with the required context.

Abstract: Computer implemented method, system and computer program product for searching for a class in a data processing system having classloaders organized in both a classloader hierarchy and a classloader network. A computer implemented method for searching for a class in a data processing system having classloaders organized in both a classloader hierarchy and a classloader network includes receiving a request to load a class at a request receiving classloader in the classloader hierarchy. The request to load a class is forwarded to a gateway classloader in the classloader network, wherein the gateway classloader is also in the classloader hierarchy. The requested class is then searched for in the classloader network.

Abstract: In a Java-based environment, a dynamic proxy runtime provides a client with the ability to asynchronously invoke an interface method, thereby unblocking the client and allowing it to perform other tasks while waiting for results to be returned from the runtime. The original interface is not redefined nor is the real target object implementation modified. Rather, the runtime defines rules which the client employs to define an additional asynchronous interface to supplement the original interface.
