You mean "proxy".   Yes, Nginx is a proxy.

server {
   server_name localhost;
   listen 8080;

   location /rails {
       proxy_pass http://localhost:3000;
       include proxy.conf; # other proxy settings - see docs

   location / {
       proxy_pass http://localhost:5984;
       include proxy.conf; # other proxy settings - see docs

I think I'd not want to send *anything* that isn't under /rails to
CouchDB, but that's what you asked for.

Probably most anyone who's read the documentation on proxying:

Nginx is a true proxy.   Squid and Varnish are *caching* proxies, Nginx
has some caching capabilities as well, although not as sophisticated
(nor as complicated).
