The registered VERSION-CONTROL request method from the IANA HTTP Method Registry.

VERSION-CONTROL is not safe and idempotent according to the IANA registry. Use it only when the target protocol defines its semantics and the intermediary chain supports it.

Request (http)

VERSION-CONTROL /resource HTTP/1.1
Host: example.com

VERSION-CONTROL is a registered extension method rather than a general browser/API default. Its registry properties describe the intended effect, not whether every implementation supports it.

Common mistakes

  • Assuming registration means that browsers, proxies, frameworks, or APIs support the method automatically.
