HTTP Engine
CMS employs the Netscape Enterprise Server as its HTTP engine. It provides the
entry point for users/applications of all types to access CMS's functions. As
discussed in the System Overview, CMS provides three types of entry points, each
serving one or more interfaces:
• End-Entity Entry Point— provides entry point for end-entity and server
certificate enrollments of all types. A set of customizable HTML forms are
provided at this port for CA and RA end-entity users for different types of
enrollment, renewal, revocation, or certificate pick-up activities. OCSP
