This session focuses on how to build an http proxy for the ArcGIS Server REST API that intercepts layer queries to dynamically join additional data onto the ArcGIS Server JSON response. The join can include data from different data sources as it is done InMemory within the proxy. This technique works through tunneling Remote Procedure Call parameters in a query. It allows for fine grained control of access to feature classes, enabling a server-side enforcement of rules on data visibility for different users or clients. It is working for all Esri client APIs (JavaScript, Flex, Silverlight), also this approach means minimal development effort on the client-side. The session includes the demonstration of the design of the proxy and request processing, a short live code demo as well as implementation patterns and tips for your server platform of choice.
