Description

SLING-7140 added a feature to support redirects to external uri of a resource if available. This handled by StreamRendererServlet. See [1]. As per the current implementation, if there's a uri available, a redirect is done for a http HEAD request as well. This can be problematic for clients which expect the response as sent by the servlet as of now if the response is different from the redirected HEAD request.

Would it be correct to handle the HEAD request before the redirect so that its current behavior is retained?
