Abstract: A system for exchanging information content between a back-end system within a restricted access environment and an end-user includes a front-end system and a manager node outside of the restricted environment, and an access node within the restricted environment. The front-end system executes a mini-application to output query data, wherein the mini-application is created using a mini-application designer, builder and plugin. The manager node receives the query data and applies business logic and connection parameters to generate a request for the information content in a first format. The manager node communicates the request to the access node in the first format. The access node converts the request to a second format particular to the back-end system, and conveys the request to the back-end system. Responses are received at the access node from the back-end system, converted to the first format and sent to the front-end system.
