Executing dynamically assigned functions while providing services

A server system comprising one or more functional processing blocks and one or more computer-readable media having computer-executable instructions for implementing a method for dynamically applying one or more filtering actions while executing any of the one or more functional processing blocks, wherein the method comprises:

• within a server system providing one or more services in response to a client request, a step for identifying one or more functional processing blocks where one or more filtering actions may be applied to one or more requests directed to the one or more services, wherein the functional processing blocks are identified within a plurality of processing layers of the server, the plurality of processing layers including at least a parsing layer;
• for at least one of the one or more functional processing blocks, a step for dynamically associating at least one filtering action, the filtering action configured to terminate further processing based on content in the request;
• a step for checking whether or not any filtering action has been associated with a particular functional processing block during execution of the particular functional processing block;
• and
• during execution of any functional processing block with one or more associated actions, a step for applying the one or more associated filtering actions by terminating further processing when the request contains particular content.
