NAME

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

VERSION

       version 0.028

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.

PERL VERSION

       This library should run on perls released even a long time ago.  It should work on any
       version of perl released in the last five years.

       Although it may work on older versions of perl, no guarantee is made that the minimum
       required version will not be increased.  The version may be increased for any reason, and
       there is no promise that patches will be accepted to lower the minimum required perl.
