The auth_request does not supports query string/arguments

[rustler2000.livejournal.com]

Having in config:

auth_request /users/v1/auth?usergroup=devel;

The debug log from nginx shows:

2013/01/01 01:52:49 [notice] 1607#0: *125 "^/users/(.*)" matches "/users/v1/auth?usergroup=devel", client: 10.9.96.2, server: localhost, request: "GET /runner/v1/status HTTP/1.1", subrequest: "/users/v1/auth?usergroup=devel", host: "10.9.96.81"
2013/01/01 01:52:49 [notice] 1607#0: *125 rewritten data: "/v1/auth?usergroup=devel", args: "", client: 10.9.96.2, server: localhost, request: "GET /runner/v1/status HTTP/1.1", subrequest: "/users/v1/auth?usergroup=devel", host: "10.9.96.81"

The strace on upstream shows:

recv(6, "GET /v1/auth%3Fusergroup=devel H"..., 8192, 0) = 507

As it seen - the question mark separating path and query got urlencoded and whole query string became part of path.

Checking the code of auth_request seems that subrequest made w/o taking care of args - there is NULL passed.
