   The Hypertext Transfer Protocol Status Code 462 (Out For Lunch)


Abstract

   This document specifies a Hypertext Transfer Protocol (HTTP) status
   code for use when a human-backed server resource is unavailable as a
   consequence of said human participating in a process of consuming
   nutritional substances.

1. Introduction

   This document specifies a Hypertext Transfer Protocol (HTTP) status
   code for use when a server operation internally utilizes a resource
   implemented in flesh and bone and said resource is currently having
   lunch or is in a post-lunch RESTful state, therefore unable to 
   provide the required resource, thus forcing the server to deny 
   access to the resource or to a set of resources which includes the
   requested resource.

   This status code can be used to provide transparency in circumstances
   where service availability may affect client operations. This
   transparency may be beneficial to end users.

2.  Requirements

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "APRIL", "FOOL", and "DESSERT" in this
   document are to be interpreted as described in [RFC2119]. 

3. 462 Out For Lunch

   This status code indicates that the server is denying access to the
   resource as a consequence of a required human dependency having
   lunch. This status code is not to be confused with status code 
   "461 Out To Lunch" which has to do with server behavior under the 
   influence of cosmic rays when financial considerations have made the
   administrator decide against investing in error-correcting (ECC)
   server random access memory. 

   A human backed resource may be manifested in ways including but not
   limited to: a senior dead-tree archive manager, a microfilm squinter,
   an adidas conveyor, a ticket pusher or a ticket dodger or a
   Just-In-Time (JIT) backend feature developer.

4. Security Considerations

   Server resources addressed with the "coffee:" URI scheme as specified
   in RFC2324 MUST NOT return status code 462, as a HTCPCP/1.0 (Hyper
   Text Coffee Pot Control Protocol) device is expected to be autonomous
   and not utilize humans in its implementation. Such HTTP responses are
   to be considered potentially malicious.

   Clients cannot rely upon the use of the 462 status code. It is
   possible that certain resources utilized by the server might wish to
   avoid transparency, and not disclose that they have left the premises
   in order to dine at the local gentlemen's club.

5. International Considerations

   The use of the 462 status code implies temporary unavailability of
   the resource named in the request. It is expected that a later
   request for the resource may succeed if the resource has recovered
   from the digestive condition.

   When an attempt to access a resource fails with status 462, it is to
   be expected that the recovery time of the server is highly locale
   dependent. In a worst case scenario the situation might involve a six
   course meal with DESSERT and a post-nourishment RESTful period also
   known as a siesta.
