1. Introduction

This document registers those Hypertext Transfer Protocol (HTTP) methods that have been defined in RFCs other than [RFC7231] before the IANA HTTP Method Registry was established.

2. Security Considerations

There are no security considerations related to the registration itself.

Security considerations applicable to the individual HTTP methods ought to be discussed in the specifications that define them.

3. IANA Considerations

The table below provides registrations of HTTP method names that have been added to the IANA "Hypertext Transfer Protocol (HTTP) Method Registry" at <> (see Section 8.1 of [RFC7231]).
