I’m using Nginx (.7.x) as a simple proxy where a couple of FastCGI
applications acts as lookup tables. These apps returns which proxy
backend that should have the request through X-Accel-Redirect - eg /
backend1/$new_uri. Finally I catch these in location matches and pass
the request along with proxy_pass.
Since i scrub the $new_uri somewhat, I want to send additional info
as a header back to Nginx, but I can’t make this work. How do I pass
headers from FastCGI back to Nginx?
