Abstract: The invention includes a system and method for logging network server data such as data relating to client requests. In accordance with the invention, end users of a server program can create one or more logging modules, each having a predefined interface that is defined by the server program. In response to client requests, the server program calls logging modules that have been designated by a system administrator, and passes potential log data to the logging modules. In response to receiving the potential log data, each logging module makes its own decision regarding (a) whether to make a log entry, (b) which data should be included in the log entry, and (c) the format that is used for recording the log data. In this way, end users are not constrained to any given logging format or set of logging criteria.
