EDGE SIDE COMPONENTS AND APPLICATION PROGRAMMING ENVIRONMENT FOR BUILDING AND DELIVERING HIGHLY DISTRIBUTED HETEROGENOUS COMPONENT-BASED WEB APPLICATIONS

摘要

A method is provided for processing an application on an edge server, wherein the application comprises a set of defined presentation, code and data components, each of which are preferably URI-addressable objects. In response to a client request, the presentation, code and data components are processed according to a set of metadata to generate a response, and the response is delivered to the client. The presentation components are typically content such as HTML fragments, WML fragments, or some combination thereof. The code components are typically Java servlets or beans, XSLT style sheets, or some combination thereof. The data components are typically XML files, native database formatted files, and the like. Each of the presentation, code and data components may have a distinct management profile, cacheability profile, deployment profile, invalidation profile, and security profile. These profiles are settable via metadata or other similar means. Using this framework, heterogenous components may be composed into other components and complete applications or services.
