I don't think there's an RFC or other specification because it seems to be a non-standard header. It's the server-side equivalent of HTML META refresh and it works in Mozilla 1.7.3, Firefox 1.0, Opera 7.54, Opera 8.02 and Internet Explorer 6.0 SP1 on Windows 2000 (see the "Failure" mentioned above; if you want to test in other browsers, see the link at the bottom of http://purl.org/NET/error404/xp/scripting/redirect/index.htm). When Googling for info about this header, you always end up with results about HTML META refresh, so it takes some time to find references. According to http://www.w3.org/Protocols/HTTP/Issues/http-wg.html, Netscape used this header already in 1995. It is also discussed in "An Exploration on Dynamic Contents" by Netscape (http://wp.netscape.com/assist/net_sites/pushpull.html). In 1997 (a long time ago, I know), someone even did a count on frequency of headers and meta attributes: http://vancouver-webpages.com/META/bycount.shtml. Another list of headers is at http://vancouver-webpages.com/META/index.shtml, and it mentions the relevant RFC if there is one.
