How to make two sequential requests

Server NGINX
1

Hi all,

when a client request arrives
I have to do two requests to two different real servers(A, B) in order.
The second request, which is to B, is created based on A’s response on
the fly.

Any ideas?

Thanks very much

Return in A’s response X-Accel-Redirect header which points to B.
