     345<section title="Example: Entity Tags varying on Content-Negotiated Resources" anchor="example.entity.tag.vs.conneg">
     346<t>
     347   Consider a resource that is subject to content negotiation (&content-negotiation;),
     348   and where the representations returned upon a GET request vary based on
     349   the Accept-Encoding request header field (&header-accept-encoding;):
     350</t>
     351<figure><preamble>>> Request:</preamble><artwork type="message/http; msgtype=&#34;request&#34;"  x:indent-with="  ">
     352GET /index HTTP/1.1
     353Host: www.example.com
     354Accept-Encoding: gzip
     355
     356</artwork></figure>
     357<t>
     358   In this case, the response may use the gzip Content Coding or not.
     359   If it does, it might look like that:
     360</t>
     361<figure><preamble>>> Response:</preamble><artwork type="message/http; msgtype=&#34;response&#34;"  x:indent-with="  ">
     362HTTP/1.1 200 OK
     363Date: Thu, 26 Mar 2010 00:05:00 GMT
     364ETag: "123-a"
     365Content-Length: <x:length-of target="exbody"/>
     366Vary: Accept-Encoding
     367Content-Type: text/plain
     368
     369<x:span anchor="exbody">Hello World!
     370Hello World!
     371Hello World!
     372Hello World!
     373Hello World!
     374</x:span></artwork></figure>
     375<t>
     376   A variant that does use gzip Content Coding would be:
     377</t>
     378<figure><preamble>>> Response:</preamble><artwork type="message/http; msgtype=&#34;response&#34;"  x:indent-with="  ">

     390    <x:h>Note:</x:h> Content Codings are a property of the response
     391    entity, thus affect the Entity Tag. An alternative are Transfer
     392    Codings (&transfer-codings;) which apply only the transfer of
     393    the message, and thus do not require assigning distinct entity tags.
