<p>服务器使用 HTTP 响应头 <code><strong>Accept-</strong></code><strong><code>Patch</code></strong> 通知浏览器请求的媒体类型(media-type)可以被服务器理解。</p>

<p><strong><code>Accept-Patch</code></strong> in response to any method means that PATCH is allowed on the resource identified by the Request-URI. Two common cases lead to this:</p>

<p>A server receiving a PATCH request with an unsupported media type could reply with  {{HTTPStatus("415")}} <code>Unsupported Media Type</code> and an Accept-Patch header referencing one or more supported media types.</p>

<ul>
 <li>
  <p>An IANA registry maintains <a class="external" href="http://www.iana.org/assignments/http-parameters/http-parameters.xml#http-parameters-1">a complete list of official content encodings</a>.</p>
 </li>
 <li>Two others content encoding, <code>bzip</code> and <code>bzip2</code>, are sometimes used, though not standard. They implement the algorithm used by these two UNIX programs. Note that the first one was discontinued due to patent licensing problems.</li>
