spaces in URI

[cgarver]

Glad to do so!

from nginx.conf
    upstream backendcms  {
        server 172.26.161.230;
    }

from my location specific conf
location ~* ^/us(.*)? {
    proxy_set_header Host xxx.xxx.xxx;
    proxy_pass       http://backendcms$1;
    subs_filter     .....
}

It truly is the white-space causing the issue because I copied the
"Member Images" folder to "Member-Images".  Trying the URI with the
hypen works and with the %20 does not.
