On Windows, trailing dot is not significant and is ignored by 
filesystem accesses, so it is normalized away.  See here for more 
details:

If you want nginx to preserve URI of a request exactly as it was 
provided by the client - make sure to use proxy_pass without an 
URI compontent, that is:

    location / {
        proxy_pass http://backend;
    }

Note no trailing "/" after "backend".
