Hi All,
I’m trying to configure a reverse proxy in Nginx, which receives a HTTP
request and call a HTTPS URL. When we change the config to call a HTTP

Here is the error:

Invalid URL

Invalid URL

The requested URL "/buy-later/buy-later/?customerId=123123", is invalid.

Reference #9.9cd8f648.1409160431.4f0536 </HTML

Here goes the current version:
nginx version: nginx/1.4.6 (Ubuntu)

Here goes the config:
server {

server_name localhost;

location /api/v1/buy-later {
  proxy_set_header Host $host;
  proxy_set_header X-Real-IP $remote_addr;
  proxy_set_header X-Forwarded-for $proxy_add_x_forwarded_for;
  proxy_set_header X-Forwarded-Proto $scheme;
  proxy_set_header User-Agent $http_user_agent;


Any help is appreciated. Thanks!
