Methods, system and computer program products for establishing a connection to a network device which does not have an assigned network address. A connection is established from a configuring device to the network device utilizing an unassigned network address for the network to which the network device is attached irrespective of whether the network device is attached to a network local to or remote from the configuring device. The network device may be configured utilizing the established connection. A network address may also be assigned to the device irrespective of whether the network device is attached to a network local to or remote from the configuring device.

Methods, systems and computer program products for communicating with unconfigured network devices on remote networks

When multiple copies of a software program reside on a single machine and need to cooperate with each other to coordinate certain aspects of their execution, an election process is conducted to elect one of the copies as a master or supervisor copy, with the non-elected copies becoming slave or subordinate copies. Since only one of the programs can succeed in being assigned the supervisor port number, the first program to have its socket assigned to the supervisor port number becomes the supervisor (e.g., the master) program; the other programs respond to the failure of their request by assuming the role of a subordinate (e.g., a slave) program.

A method, system, and computer program product for caching dynamically generated content (including, but not limited to, dynamically generated Web pages), as well as determining when the cached content should be invalidated or purged. Rather than caching the generated datastream (i.e. the end result of the computations used in the dynamic generation process) as in the prior art, the interim results of computations (such as a generated bean instance or object, where the interim results may be stored using properties and methods) are cached according to the present invention. The input properties used to generate the bean or object, along with the input property values, are used to distinguish among cached instances and thereby identify when a cached instance may be used to respond to a subsequent request for the same content. Re-execution of the business logic of the bean or object may then be avoided, using the cached bean's or object's output properties to generate the content response. Application-specific, developer-defined criteria may be used in the cache invalidation determination.
