+<!-- Some of our APIs redirect to
+     worldwidetelescope.org/webclient/default.aspx, passing query string
+     parameters. Until we can update the API calls, we need to redirect from
+     default.aspx to `./`, honoring the query strings. Unfortunately we
+     use a static file server to serve everything within the /webclient/ tree
+     and I can't find a way to achieve a server-side redirect for just that
+     one URL path. So we have to do it in JavaScript.
+
+     Note also that when we publish this file to our Azure Blob Storage, we
+     need to specially set its Content-Type so that it's treated as HTML. -->
