Re: [Htmlunit-user] Redirect to relative address in a frame causes loop

Assuming that this works in the browser for you then it's likely a bug with no
simple fix (you could pull latest CVS and make a custom RefreshHandler but it would
not be a generic fix because the data it's given would be incorrect).
That seems like a strange thing to specify in a Location header for the response you
expect. Is there a spec anywhere on interpretation of incomplete URIs in HTTP
Location headers?
