A method is presented for obtaining information from a client for the benefit of a server using a particular communication protocol that the server does not implement. A primary server receives a client-generated request, and the primary server sends a first request to a secondary server as part of the processing of the client-generated request. While processing the first request, the secondary server determines a need for data obtainable from a client application that supports user interaction using a communication protocol for which the secondary server is not configured to implement. The secondary server sends a second request to the primary server for obtaining data that results from using the communication protocol. The secondary server subsequently receives the resulting data and continues to process the first request using the resulting data, after which the secondary server returns a response for the first request to the primary server.
