Revision 1111815 of TE

<div>{{HTTPSidebar}}</div>

<p>The <code><strong>TE</strong></code> request header specifies the transfer encodings the user agent is willing to accept. (you could informally call it <em><code>Accept-Transfer-Encoding</code></em>, which would be more intuitive).</p>

<p>See also the {{HTTPHeader("Transfer-Encoding")}} response header for more details on transfer encodings. Note that <code>chunked</code> is always acceptable for HTTP/1.1 recipients and you that don't have to specify <code>"chunked"</code> using the <code>TE</code> header. However, it is useful for setting if the client is accepting trailer fields in a chunked transfer coding using the "trailers" value.</p>

 <p>When multiple transfer codings are acceptable, the <code>q</code> parameter of the <a href="/en-US/docs/Glossary/Quality_values">quality value</a> syntax can rank codings by preference.</p>
