<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,<title>Testcase</title><p>This
|
|
is a testcase</p></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>Grüße aus Schlägl</literal>
|
|
whereas omitting the charset attribute might lead to something like
|
|
<literal>Gr??e aus Schl?gl</literal>
