A system for optimizing server response time to polling for new e-mail messages by a client. A cache of memory storing information about a user for responding to polling queries is maintained by the server. When a polling session is established, the client transmits a query to the server. The server receives the query and reads the cache to retrieve the user information that includes the response to the query. The response read from the cache is then transmitted to the client.
