Proxying GET parameters through a static image using NGINX?

Question

Nginx

There is the following task:
There is a picture, it should be given by Nginx as static. But it can be called with different GET parameters and these parameters must be proxied to another server.
Is it possible and how to implement it?

Answer 1

Use X-Accel-Redirect.

Answer 2

location can use regular expressions, you can parse everything and substitute it where you need it

Answer 3

You need to do almost the same thing. Subscribed for replies.

Answer 4

Can you be more specific about what and how? It is not entirely clear with the proxying of parameters to another server for statics.

Answer 5

You can use the eval or echo modules to send a background subrequest while serving up a picture. But I'd rather parse a custom pixel.access.log than fence such a garden with a backend and modules.
