+<title>WebPerl Sync HTTP Demo</title>
+
+<!--
+This is a demo of dynamically loading modules via synchronous
+XMLHttpRequests.
+
+WARNING: Please note that https://xhr.spec.whatwg.org/ says:
+"Synchronous XMLHttpRequest outside of workers is in the process of
+being removed from the web platform as it has detrimental effects to
+the end user’s experience. (This is a long process that takes many
+years.)"
+
+The method was first described by LanX at
+https://www.perlmonks.org/?node_id=1225490
+Thank you! :-)
