 I'm using cloud9 ide, which listens on a local port @ / and I'm proxying to it via proxy_pass.  I want to add a second instance, listening on another local port and to be able to use it from code.mydomain.org/myapp.  My / location works perfectly, but I am stumped setting up a second proxy using a location other than /.
 
 
 server {
        listen 80;
        server_name code.mydomain.org;
 
 
 
        location / {
                 proxy_pass http://localhost:3131;
                 include /etc/nginx/proxy_params;
        }
 
-       location /myapp/ {
+       location ^/myapp/ {
                 rewrite /myapp(.*) $1 break;
                 proxy_pass http://127.0.0.1:3132;
                 include /etc/nginx/proxy_params;
        }
 
 }
