Enterprise client-server system and methods of providing web application support through distributed emulation of websocket communications

Abstract

A system enabling service communications in distributed Web applications between servers otherwise inaccessible due to cross-origin security restrictions in pre-HTML5 compliant Web-browser clients. A Web-browser client executes a client-side Web application received from a source origin server having a defined source origin and requests connections to request identified Web-application services. Execution of an emulation client library establishes a bidirectional capable HTTP-based communications connection between the Web-browser client and a gateway server, having a target origin outside the scope of the source origin, providing access to the request identified Web-application service. The bidirectional capable HTTP-based communications connection includes a cross-origin communications bridge providing a secure communications path between the source and target origins. The gateway server can establish an HTML5 compliant connection to a target defined service, provided by a target server, having a predefined relation to the request identified Web-application service.
