Hi,

Previously, I wrote a module to make a subrequest to backend. nginx.conf like that:

location /file {
nphase_uri /dummy;
nphase_set_uri_var $np_uri http://backend;
}

location /dummy {
proxy_pass $np_uri;
}

The module could send original URI "http://localhost/file/abcd.txt" to backend to process.
And the module could get response from backend and decide to continue or refuse.

But now This fix disabled sending original URI to backend.

*) Bugfix: a "proxy_pass" directive without URI part might use original
request after redirection with the "try_files" directive.

If we need to send same request to backend, we must use named location. But it
seems that named location is not support in subrequest. The named location only
processed in try_files phase.

Following configuration would not work, for the subrequest send a request "GET /dummy"
rather than original URI.

location /dummy {
try_files /dummy @named;
}
location @named {
proxy_pass $np_uri;
}

So how do I make it work?
