+    \class QHttpHeader
+    \obsolete
+    \brief The QHttpHeader class contains header information for HTTP.
+
+    \ingroup network
+    \inmodule QtNetwork
+
+    In most cases you should use the more specialized derivatives of
+    this class, QHttpResponseHeader and QHttpRequestHeader, rather
+    than directly using QHttpHeader.
+
+    QHttpHeader provides the HTTP header fields. A HTTP header field
+    consists of a name followed by a colon, a single space, and the
+    field value. (See RFC 1945.) Field names are case-insensitive. A
+    typical header field looks like this:
+    \snippet doc/src/snippets/code/src_network_access_qhttp.cpp 0
+
+    In the API the header field name is called the "key" and the
+    content is called the "value". You can get and set a header
+    field's value by using its key with value() and setValue(), e.g.
+    \snippet doc/src/snippets/code/src_network_access_qhttp.cpp 1
+
+    Some fields are so common that getters and setters are provided
+    for them as a convenient alternative to using \l value() and
+    \l setValue(), e.g. contentLength() and contentType(),
+    setContentLength() and setContentType().
+
+    Each header key has a \e single value associated with it. If you
+    set the value for a key which already exists the previous value
+    will be discarded.

+    \class QHttpRequestHeader
+    \obsolete
+    \brief The QHttpRequestHeader class contains request header information for HTTP.
+
+    \ingroup network
+    \inmodule QtNetwork
+
+    This class is used in the QHttp class to report the header
+    information if the client requests something from the server.
+
+    HTTP requests have a method which describes the request's action.
+    The most common requests are "GET" and "POST". In addition to the
+    request method the header also includes a request-URI to specify
+    the location for the method to use.
+
+    The method, request-URI and protocol-version can be set using a
+    constructor or later using setRequest(). The values can be
+    obtained using method(), path(), majorVersion() and
+    minorVersion().
+
+    Note that the request-URI must be in the format expected by the
+    HTTP server. That is, all reserved characters must be encoded in
+    %HH (where HH are two hexadecimal digits). See
+    QUrl::toPercentEncoding() for more information.
+
+    Important inherited functions: setValue() and value().
