Techniques for responding to a request for a resource on a network include receiving at a server the request from a client process for the resource. The server transmits a set of request information items associated with the request. In response to this transmission, a database server receives at least a subset of the set of request information items. Within the database server, at least one particular request information item of the subset is used as a key to identify a routine. The routine is executed to generate a set of access information items. The server responds to the request based on the set of access information items. Using these techniques, the server responds to the request differently without taking the server offline, by changing the routine indicated within the database server.
