1. Scope

   The Open Pluggable Edge Services (OPES) framework documents several
   application-agnostic mechanisms such as OPES processor and endpoints
   communications [RFC3897] or OPES callout protocol [RFC4037].  This
   document extends those generic mechanisms for adaptation of a
   specific application protocol, HTTP [RFC2616].  Together,
   application-agnostic OPES documents and this HTTP profile constitute
   a complete specification for HTTP adaptation with OPES.

   The primary sections of this document specify HTTP-specific
   extensions for the corresponding application-agnostic mechanisms
   documented elsewhere.
