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 a standards track RFC. Protocol Quality This document has been reviewed by members of the email@example.com mailing list and by the PKIX working group chairs. This document was reviewed by Russ Housley for the IESG.
