"Object moved to here" message in an empty page

I had to investigate a situation where a message of "Object moved to here", where "here" was a link, appeared in our ASP.Net application. First of all, we don't have that message in the app, it appears it is an internal message in ASP.Net, more exactly in HttpResponse.Redirect. It is a hardcoded HTML that is displayed as the response status code is set to 302 and the redirect location is set to the given URL. The browser is expected to move to the redirect location anyway, and the displayed message should be only a temporary thing. However, if the URL is empty, the browser does not go anywhere.

In conclusion, if you get to a webpage that has the following content:
<html><head><title>Object moved</title></head><body>
<h2>Object moved to <a href="[url]">here</a>.</h2>
then you are probably trying to Response.Redirect to an empty URL.
