<para>Data URLs allow small document data to be included in the URL itself. This is useful for very small HTML testcases or other occasions that do not justify a document of their own.</para>

<para><userinput>data:,foobar</userinput> (note the comma after the colon) will deliver a text document that contains nothing but <literal>foobar</literal> </para>

<para>The last example delivered a text document. For HTML documents one has to specify the MIME type <literal>text/html</literal>: <userinput>data:text/html,&lt;title&gt;Testcase&lt;/title&gt;&lt;p&gt;This is a testcase&lt;/p&gt;</userinput>. This will produce exactly the same output as if the content had been loaded from a document of its own. </para>

<para>Specifying alternate character sets is also possible. Note that 8-Bit characters have to be escaped by a percentage sign and their two-digit hexadecimal codes: <userinput>data:;charset=iso-8859-1,Gr%FC%DFe aus Schl%E4gl</userinput> results in <literal>Gr&uuml;&szlig;e aus Schl&auml;gl</literal> whereas omitting the charset attribute might lead to something like <literal>Gr??e aus Schl?gl</literal> </para>

<para><ulink url="http://www.ietf.org/rfc/rfc2397.txt">IETF RFC2397</ulink> provides more information.</para>
