A processor-implemented method manages a data cache for a computer system. One or more processors maintain a cache for one or more data resources requested by a client process. In response to a request from the client process for a cached data resource, the processors send a first request to a server process for the data resource, and a second request to the server process for an indication of whether or not the data resource has been modified since the data source was most recently cached. Responses to the first or second requests from the server process are compared with the cached data resources so as to identify whether the response to the second request is inaccurate. One or more processors disable caching for the data resource in response to a predetermined number of inaccurate second requests associated with the data resource being identified.

Managing a data cache for a computer system

A computer receives a heartbeat message that includes both program reset information and at least one segment, of the heartbeat message, that is configured to indicate whether or not a first program is functioning correctly. The computer determines if the heartbeat message includes the indication that the first program is functioning correctly. If the computer determines that the heartbeat message indicates that the first program is functioning correctly, then the computer sends a data stream to the first program.

Monitoring hierarchical container-based software systems

Disclosed is a program for validating a web cache independent of an origin server. A computer in between a client computer and the origin server computer receives a request for a resource and an entity tag (ETag) corresponding to the request. The computer forwards the request to the origin server and subsequently receives the resource. The computer generates an ETag for the received resource and compares the generated ETag to the ETag corresponding to the request. If the ETags match, the computer sends an indication toward the client computer that the resource has not been modified.

A method and apparatus for voice message editing, particularly a method and apparatus for splicing voicemails sections together. A system, method and computer program product are described for forming a voice message on an interactive voice response system (IVR) spoken by a user including recording a first voice message where the user speaks the first voice message but makes an error in a last portion of the first voice message. A second voice message is recorded where the user speaks the last portion again without the error. Splice points are determined in the first and second voice messages. The first and second voice messages are spliced at the splice points such that the spliced first and second voice message is a continuous voice message including the last portion but not including the error.

Method and apparatus for voice message editing

A method and arrangement for improved speech recognition in a telephonically challenging speakerphone in-car environment. The method includes receiving a signal from a microphone representative of speech to be recognized, performing detection of a transition in the signal indicative of switch on of the microphone, and, in response to the detection, performing speech recognition on the signal with reduced contribution from an initial portion thereof. The initial portion may be treated as optional speech, the speech recognition may be performed with a predetermined redundant sound, and a user may be requested to speak the predetermined redundant sound when speech recognition has fallen below a predetermined threshold. Thus, recognition may be made possible when otherwise it would not be possible, recognition match scoring will be increased as the low weighting given by deleted initial sounds will be eliminated and therefore confusion of the recognized phrase will be reduced.
