Fail to strip upstream_db_path from package urls

[joshgordon]

Hello,

The NPM mirror that I'm using has a /npm at the end of the url, so I used upstream_db_path in the config.json to make it work. However, when npm-lazy-mirror proxies back the URLs for the packages, it doesn't strip the /npm out, causing them to 404.

I devised a temporary workaround using nginx (since I'm reverse proxying through that anyways) as follows:

server {
  listen 8080;
  location / {
    proxy_pass http://localhost:20000;
  }
  location ~* /npm(/.*) {
    return 301 $1;
  }
}

The proxy should strip the upstream_db_path from the path to the packages before pushing to the client.
