752	try_files + subrequest + proxy-handler problem	openid.yandex.ru/emychlo		"When using subrequests with try_files the following behaviour is observed.

   }
}}}


Assuming /tmp/tres exists, a request to

http://127.0.0.1:8080/uno

returns **""uno  tres ""**, not **""uno  duo ""** or  **""tres tres ""**.

I.e., main request assumes that the request URI is unmodified and passes original request URI, ""/uno"".
But in a subrequest the URI is modified and nginx uses modified URI, ""/tres"".

This is believed to be a bug, and one of the following should be done:

- `try_files` should reset the `r->valid_unparsed_uri` flag if it modifies the URI;
- or `try_files` should not modify the URI at all.
