Systems, methods, and other embodiments associated with content invalidation are described. One example method includes parsing a response to identify an invalidation directive. Then if identified, invalidating cached content from a cache memory that corresponds to the content identified by an invalidation directive.

Response header invalidation

Systems, methods, and other embodiments associated with intelligently processing log messages are described. In one embodiment, a computer-implemented method includes analyzing, by a logging appliance that includes at least hardware, communications received from a plurality of handlers to determine whether at least one of the communications indicates an error has been encountered by one of a plurality of components associated with the plurality of handlers. The method includes scheduling a subset of the plurality of handlers to provide reports that include a detailed set of log messages in response to detecting the error. The subset of the plurality of handlers includes handlers that are associated with the error.

Logging incident manager

Systems, methods, and other embodiments associated with processing regular expressions are described. One example method includes analyzing a rule for a regular expression and deleting the regular expression.

Regular expression optimizer

Systems, methods, and other embodiments associated with intelligently gathering log messages are described. In one embodiment, a computer-implemented method includes collecting, by a logging handler associated with a component, log messages according to two different granularities for logging messages. The two different granularities include a fine granularity and a coarse granularity. Collecting the log messages according to the fine granularity includes storing log messages in an incident buffer. The method includes, in response to detecting an error at the component, (i) freezing the incident buffer to preserve log messages present in the incident buffer, and (ii) communicating log messages that are collected according to the coarse granularity that are stored in a regular buffer to a logging appliance.

Fine and coarse granularity logging handler

Systems, methods, and other embodiments associated with content invalidation are described. One example method includes providing an invalidation directive in a header of a response.

Systems, methodologies, media, and other embodiments associated with processing network communications are described. One embodiment of a method includes processing data requests including changing an input/output (I/O) communications type for processing the data requests.

Changing I/O types for processing data requests

Systems, methods, and other embodiments associated with event logging are described. One example method includes collecting request-based event log data associated with processing a request and temporarily storing the event log data in a memory. In the event of an error, the event log data is transferred to a storage device.

Request based logging

Systems, methods, and other embodiments associated with shared error searching for web resource requests are described. A web resource request that includes one or more request strings is received and a error detection directive that identifies a first type of error to be located in a specified request string component is accessed. At least a portion of a first request string that corresponds to the specified request string component is searched, in a single pass, for the first type of error and other types of errors. Results with respect to the first error type are returned while occurrences of the first and other types of errors for are recorded for responding to subsequent error detection directives. Thus, a subsequent error detection directive for the other types of errors in the first request string component may be processed without re-searching the portion of the first request string already searched with respect to the first error detection directive.
