Input Headers. - headers_more_module.

[David | StyleFlare]

Thank You

So this worked.

The question is then if I am setting a value in /auth

When does it get actually set?

postgres_set $pg_server 0 0 required;

Then in my location block;
I do

more_set_input_headers 'X-Server-ID: $pg_server';

When is $pg_server actually set?

Thanks.
