+Rendered HTML that contains social media headers describing the object of the given url.
+Please keep in mind that the response contains partial ``<html>`` and ``<head>`` tags to allow the response to contain a language attribute in the root tag.
+This needs to be equalized in the server-side include e.g. as follows:
+
+.. code:: html
+
+    <!-- Nginx Server Side Include template for dynamic social media previews -->
+    <!--# if expr="$render_title = yes" -->
+    <!--# include virtual="/proxy/socialmeta/$request_uri" -->
