Redirect uploaded files to another server, using nginx
- by Serg ikS
I am creating a web service of scheduled posts to some soc. network.Need help dealing with file uploads under high traffic.
Process overview:
User uploads files to SomeServer (not mine).
SomeServer then responds with a JSON string.
My web app should store that JSON response.
Opt. 1 — Save, cURL POST, delete tmp
The stupid way I made it work:
User uploads files to MyWebApp;
MyWebApp cURL's the file further to SomeServer, getting the response.
Opt.2 — JS magic
The smart way it could be perfect:
User uploads the file directly to SomeServer, from within an iFrame;
MyWebApp gets the response through JavaScript.
But this is(?) impossible due to the 'Same Origin Policy', isn't it?
Opt. 3 — nginx proxying?
The better way for a production server:
User uploads files to MyWebApp;
nginx intercepts the file uploads and sends them directly to the SomeServer;
JSON response is also intercepted by nginx and processed by MyWebApp.
Does this make any sense, and what would be the nginx config for, say, /fileupload Location to proxy it to SomeServer ?
