ASL HTTP Front End

Introduction

ASL HTTP Front End assist a layer of the system Integration and Interoperability Framework. It offers HTTP APIs to expose a subset of its JAVA API facilities for supporting high level standards. It consists of a set of servlets that support HTTP methods and operates on top of the JAVA libraries. The objective of this framework layer involves access points that cover series of services, can pass through ASL for session handling and/or expose HTTP standards compliant interfaces. The framework targets clients submitting HTTP requests and handling HTTP responses. Such clients are components external or internal to the system that have come in an agreement with the HTTP services implementers about the data/format they are expecting and the response they will be giving out, or will be implementing standard HTTP specifications offered by the HTTP front end of the system. ASL HTTP Front End is the outcome of the retrospection of the previous version of Application Services Layer HTTP API that was mandated by the need for formalization and extensibility of the framework.
