<h3>Summary</h3>

    <p>This module provides the ability to convert a response into
    an <a href="https://www.rfc-editor.org/rfc/rfc2397">RFC 2397</a> (data URL).
    </p>

    <p>Data URLs can be embedded inline within web pages using something
    like the <code class="module"><a href="../mod/mod_include.html">mod_include</a></code> module, to remove the need for
    clients to make separate connections to fetch what may potentially be
    many small images. Data URLs may also be included into pages generated
    by scripting languages such as PHP.</p>

    <div class="example"><h3>An example of a data URL</h3><p><code>
        data:image/gif;base64,R0lGODdhMAAwAPAAAAAAAP///ywAAAAAMAAw<br>

    <p>The filter takes no parameters, and can be added to the filter stack
    using the <code class="directive"><a href="../mod/core.html#setoutputfilter">SetOutputFilter</a></code> directive,
    or any of the directives supported by the <code class="module"><a href="../mod/mod_filter.html">mod_filter</a></code>
    module.</p>

    <div class="example"><h3>Configuring the filter</h3><pre class="prettyprint lang-config">&lt;Location "/data/images"&gt;

<p>This module provides no
