No, at least not for GET requests.  303 (See Other) was originally
defined as "redirect with a different method" and not fully specified.
When HTTP was standardized, 303 became "see other" for the specific
purpose of redirecting a non-GET request to a GET of another resource.
Defining a specific purpose for 303 in response to a GET is what we
are doing right now.  There was no pre-existing usage of 303 in response
to a GET prior to the HTTPrange issue being decided.
