NAME

       HTTP::Throwable::Role::Status::NotModified - 304 Not Modified

VERSION

       version 0.027

DESCRIPTION

       If the client has performed a conditional GET request and access is allowed, but the document has not
       been modified, the server SHOULD respond with this status code. The 304 response MUST NOT contain a
       message-body, and thus is always terminated by the first empty line after the header fields.

       The response MUST include the following header fields:

       Date, unless its omission is required by section 14.18.1
           If  a  clockless  origin  server obeys these rules, and proxies and clients add their own Date to any
           response received without one (as already specified  by  [RFC  2068],  section  14.19),  caches  will
           operate correctly.

       ETag and/or Content-Location, if the header would have been sent in a 200 response to the same request
       Expires, Cache-Control, and/or Vary, if the field-value might differ from that sent in any previous
       response for the same variant

       If  the  conditional  GET  used  a  strong cache validator, the response SHOULD NOT include other entity-
       headers. Otherwise (i.e., the conditional GET used a weak validator), the response MUST NOT include other
       entity-headers; this prevents inconsistencies between cached entity-bodies and updated headers.

       If a 304 response indicates an entity not currently cached, then the cache MUST  disregard  the  response
       and repeat the request without the conditional.

       If  a  cache  uses  a  received  304 response to update a cache entry, the cache MUST update the entry to
       reflect any new field values given in the response.
