Which of following is NOT a valid HTTP Status response recognized by most browsers?

Which of following is NOT a valid HTTP Status response recognized by most browsers?

• 429 Too Many Requests
• 437 UDP sequence mismatch
• 410 Gone
• 418 I am a Teapot 

 

EXPLANATION

410, 418, and 429 are supported in all the major browsers. 

437 is made up from whole cloth... UDP isn't in the same protocol layer as HTTP, and even if it does it doesn't have sequences.

(Question grew out of my love of the 418 status code!  Yeah, it is an easily google-able question.)
