Someone posted this on MogileFS mailing list in reply to me - basically an English paraphrase/working example of the Japanese website. It still requires application level scripts to map the incoming URL to a key though.

I'm using this setup in production now for about 2 weeks and it works very well! (Perlbal leaked too much memory). You do need nginx 0.6.27 or higher for this to work. It would be really nice if nginx would support this directly by simply acting on the X-Reproxy-URL content directly because there are issues with setting headers in the reproxy situation currently. It would also be cool if it supported multiple URL's and fallback if the first URL is not available (also a Perlbal feature) i.e.

header["X-Reproxy-URL"] = "http://10.10.10.1/dev/fidfile,http://10.10.10.2/dev/fidfile"
