Hello!
It add a few of new http status code In RFC 6585(
http://tools.ietf.org/html/rfc6585), and so I add this to Nginx.
The new http status code 429(Too Many Requests) and 431(Request Header
Fields Too Large) in RFC 6585 is useful to Nginx,
because Nginx will return 400 when request header is Too Large and return
503 when too many request(in limit_req).
Blew is patch(for Nginx trunk) to use 429 replace 400 when request header
is too large,
and use 431 replace 503 when find too many request(limit_req module). in
addition to add new http status code 511.
Thanks!
