Described herein are systems and methods for client-side callbacks to server events in which a Web server receives a message indicating a client-side event. The client-side event is associated with a specific component of a client resource, the specific component being one of multiple static components of the client resource. A server-side component generates a response to the received message and implements at least a subset of logic of the specific component. In generating the response to the message, server-side logic corresponding to other static components that are different than the specific component are not used.
