    <dd>The request header is set, but only if there is no previous header

    with this name.<br />

    Available in 2.4.7 and later.</dd>

    with this name.

    <div class="note">

    The Content-Type header is a special use case since there might be

    the chance that its value have been determined but the header is not part

    of the response when <code>setifempty</code> is evaluated.

    It is safer to use <code>set</code> for this use case like in the

    following example:

    <pre class="prettyprint lang-config">Header set Content-Type "text/plain" "expr=-z %{CONTENT_TYPE}"</pre>



    </div></dd>



    <dt><code>unset</code></dt>

    <dd>The response header of this name is removed, if it exists.
