Fixed wrong URI after try_files in nested location (ticket #97). The following configuration with alias, nested location and try_files resulted in wrong file being used. Request "/foo/test.gif" tried to use "/tmp//foo/test.gif" instead of "/tmp/test.gif": location /foo/ { alias /tmp/; location ~ gif { try_files $uri =405; } } Additionally, rev. c985d90a8d1f introduced a regression if the "/tmp//foo/test.gif" file was found (ticket #768). Resulting URI was set to "gif?/foo/test.gif", as the code used clcf->name of current location ("location ~ gif") instead of parent one ("location /foo/"). Fix is to use r->uri instead of clcf->name in all cases in the ngx_http_core_try_files_phase() function. It is expected to be already matched and identical to the clcf->name of the right location.
