Abstract: A preloader works in conjunction with a web/app server and optionally a profile server to cache web page content elements or components for faster on-demand and anticipatory dynamic web page delivery. The preloader uses a cache manager to manage requests for retrievals, insertions, and removal of web page components in a component cache. The preloader uses a cache replacement manager to manage the replacement of components in the cache. While the cache replacement manager may utilize any cache replacement policy, a particularly effective replacement policy utilizes predictive information to make replacement decisions. Such a policy uses a profile server, which predicts a user's next content request. The components that can be cached are identified by tagging them within the dynamic scripts that generate them. The preloader caches components that are likely to be accessed next, thus improving a web site's scalability.

Abstract: A method and apparatus for distributing a plurality of session requests across a plurality of servers. The method includes receiving a session request and determining whether the received request is part of an existing session. If the received request is determined not to be part of an existing session, then the request is directed to a server having the lowest expected load. If, however, the request is determined to be part of an existing session, then a second determination is made as to whether the server owning the existing session is in a dispatchable state. If the server is determined to be in a dispatchable state, then the request is directed to that server. However, if the server is determined not to be in a dispatchable state, then the request is directed to a server other than the one owning the existing session that has the lowest expected load.

Abstract: The present invention provides an application virtualization framework that allows dynamic allocation and de-allocation of compute resources, such as memory. Runtime applications are pooled across multiple application servers and compute resources are allocated and de-allocated in such a way that resource utilization is optimized. In addition, objects are either stored in local memory or in a non-local memory pool depending on certain criteria observed at runtime. Decision logic uses decision rules to determine whether an object is to be stored locally or in a memory pool. Resource management logic monitors the memory pool to determine which locations are available for storing objects and how much memory is available overall in the memory pool for storing objects.

Abstract: Apparatuses and methods for accelerating web services. In accordance with a first embodiment of the present invention, the apparatus and method of the present invention are incorporated into consumer-side logic, such as, for example, in Web portal logic, and operate to accelerate web services by reducing processing overhead on the consumer side. In accordance with a second embodiment of the present invention, the apparatus and method of the present invention are incorporated into provider-side logic, such as, for example, in logic located at a Web Service Provider (WSP), and operate to accelerate web services by reducing processing overhead on the provider side.

Abstract: A system and method for delivering a web page can include receiving a web page request corresponding to a web page having cacheable content. In response to the web page request, a script can be executed to produce a template of the web page at run-time. The script can include a code block corresponding to a cacheable content fragment of the web page. A key identifying the cacheable content fragment can be inserted into the template. The template can be sent to a dynamic proxy cache. The dynamic proxy cache can insert the cacheable content fragment identified by the key into the web page. The web page including the cacheable content fragment can then be delivered to a user.
