Technical Summary

  This document defines a lightweight profile of the Online Certificate
  Status Protocol (OCSP) that can be used to allow distributed local
  provision of cashed pre-calculated OCSP responses from a central OCSP
  server.  It is intended that the normative requirements defined in
  this profile will be adopted by OCSP clients and OCSP responders
  operating in either very large scale (high volume) PKI environments or
  environments that need minimize bandwidth or client-side processing
  power (or both).  This document addresses the scalability issues, and
  defines a message profiles for and OCSP client and responder.  The
  document includes:

  1) OCSP response pre-production and distribution;
  2) Reduced OCSP message size to lower bandwidth usage; and
  3) Response message caching in OCSP responders and clients.

Working Group Summary

  The PKIX working group expressed consensus to advance the document as
  Informational RFC.
