  34 <h3>Summary</h3>
  35
  36     <p>This module provides the ability to convert a response into
  37     an <a href="http://tools.ietf.org/html/rfc2397">RFC2397 data URL</a>.
  38     </p>
  39
  40     <p>Data URLs can be embedded inline within web pages using something
  41     like the <code class="module"><a href="../mod/mod_include.html">mod_include</a></code> module, to remove the need for
  42     clients to make separate connections to fetch what may potentially be
  43     many small images. Data URLs may also be included into pages generated
  44     by scripting languages such as PHP.</p>
