<refsect1 id="desc_http_internal_redirect"><title>Description</title>
<para>This function performs internal redirect. Can be used in handling situations where HTTP level
redirection is inadequate. For example, 303 redirection offered when implementing hashless Linked
Data URIs. Instead of sending a 303 Virtuoso will redirect to the URL in "Location:" and
return 200 OK. Basically, this is like curl -iL instead of curl -i, but implemented inside Virtuoso.
</para>
<para>The function can be used directly or via URI template syntax used to construct rewrite rules
for Virtuoso virtual directories / web service endpoints.</para>
