The invention relates to a method for request processing. The method includes receiving an asynchronous request for a shared context from a first client, where a second client is subscribed to the shared context. The method further includes receiving a modification of the shared context from the second client and, determining, in response to receiving the modification, that the modification matches a criteria specified in a first request filter, where the first request filter is one of a number of request filters associated with the shared context. The method further includes obtaining the first request filter and after determining that a first condition specified in the first request filter is satisfied, initiating the transmission of the modification to the first client, where the modification is displayed at the first client.
