Incorrect REQUEST_URI for nginx internal redirects and subrequests

[W. Andrew Loe III]

If I create an action that X-Accel-Redirects to an internal url that
proxies to Passenger, the REQUEST_URI copied in to the scgi request is
the original not the new request, creating an infinite loop.

GET /archive
=> Rails response to mod_zip with list of files to zip
[/files/1, /files/2]
subrequest GET /files/1
subrequest GET /files/2

Both of these subrequest hit Passenger, but the REQUEST_URI is set to
/archive not /files/x.

Sometimes I need to X-Accel-Redirect/Subrequest to another rails
location, other times its a file on my filesystem, other times its
remote.

I have opened an issue and provided a patch.
