+
+<p>HTTP-заголовки сопровождают обмен данными по протоколу HTTP. Они могут содержать описание данных и информацию, необходимую для взаимодействия между клиентом и сервером. Заголовки и их статусы перечислены в <a href="http://www.iana.org/assignments/message-headers/perm-headers.html">реестре IANA</a>, который постоянно обновляется.</p>
+
+<p>Заголовки могут быть сгруппированы по следующим контекстам:</p>
+
+<ul>
+ <li>{{Glossary("General header", "Основные заголовки")}} <span class="tlid-translation translation" lang="ru"><span title="">применяется как к запросам, так и к ответам, но не имеет отношения к данным, передаваемым в теле.</span></span></li>
+ <li>{{Glossary("Заголовок запроса", "Заголовки запроса")}} <span class="tlid-translation translation" lang="ru"><span title="">содержит больше информации о ресурсе, который нужно получить, или о клиенте, запрашивающем ресурс</span></span>.</li>
+ <li>{{Glossary("Response header", "Заголовки ответа")}} <span class="tlid-translation translation" lang="ru"><span title="">содержат дополнительную информацию об ответе, например его местонахождение, или о сервере, предоставившем его.</span></span></li>
+ <li>{{Glossary("Entity header", "Заголовки сущности")}} <span class="tlid-translation translation" lang="ru"><span title="">содержат информацию о теле ресурса, например его </span></span><a href="https://wiki.developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Length">длину содержимого </a>или тип <a href="https://wiki.developer.mozilla.org/en-US/docs/Web/SVG/Content_type">MIME</a>.</li>
+</ul>
+
+<p>Заголовки также могут быть сгруппированы согласно тому, как <a href="https://wiki.developer.mozilla.org/en-US/docs/Glossary/Proxy_server">прокси (proxies)</a> обрабатывают их:</p>
+
+<ul>
+ <li>{{ httpheader("Connection") }}</li>
+ <li>{{ httpheader("Keep-Alive") }}</li>
+ <li>{{ httpheader("Proxy-Authenticate") }}</li>
+ <li>{{ httpheader("Proxy-Authorization") }}</li>
+ <li>{{ httpheader("TE") }}</li>
+ <li>{{ httpheader("Trailer") }}</li>
+ <li>{{ httpheader("Transfer-Encoding") }}</li>
+ <li>{{ httpheader("Upgrade") }}.</li>
+</ul>
+
+<p><strong>Сквозные заголовки</strong><br>
+      Эти заголовки должны быть переданы конечному получателю сообщения: серверу для запроса или клиенту для ответа. Промежуточные прокси-серверы должны повторно передавать эти заголовки без изменений, а кэши должны их хранить.</p>
+
+<p><strong>Хоп-хоп заголовки (Хоп-хоп заголовки)</strong><br>
+      Эти заголовки имеют смысл только для одного соединения транспортного уровня и не должны повторно передаваться прокси или кэшироваться. Обратите внимание, что с помощью общего заголовка {{httpheader ("Connection")}} могут быть установлены только заголовки переходов.</p>
