<description>Convert response body into an RFC2397 data URL</description>

<status>Extension</status>

<sourcefile>mod_data.c</sourcefile>

<identifier>data_module</identifier>

<compatibility>Available in Apache 2.3 and later</compatibility>



<summary>

    <p>This module provides the ability to convert a response into

    an <a href="http://tools.ietf.org/html/rfc2397">RFC2397 data URL</a>.

    </p>



    <p>Data URLs can be embedded inline within web pages using something

    like the <module>mod_include</module> 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>



    <example><title>An example of a data URL</title>

        data:image/gif;base64,R0lGODdhMAAwAPAAAAAAAP///ywAAAAAMAAw<br />

        hhx4dbgYKAAA7<br />

    </example>



    <p>The filter takes no parameters, and can be added to the filter stack

    using the <directive module="core">SetOutputFilter</directive> directive,

    or any of the directives supported by the <module>mod_filter</module>

    module.</p>



    <example><title>Configuring the filter</title>

        &lt;Location /data/images&gt;<br />

        <indent>

            SetOutputFilter DATA

        </indent>

        &lt;/Location&gt;<br />
