This document defines a new HTTP header field named "Expect-CT",
which allows web host operators to instruct user agents (UAs) to
expect valid Signed Certificate Timestamps (SCTs) to be served on
connections to these hosts. Expect-CT allows web host operators to
discover misconfigurations in their Certificate Transparency (CT)
deployments. Further, web host operators can use Expect-CT to ensure
that if a UA that supports Expect-CT accepts a misissued certificate,
that certificate will be discoverable in Certificate Transparency
logs.

This document is a product of the HTTP Working Group of the IETF.
