Inserting a Request header before proxying


#1

I’d like to insert a custom HTTP header (eg: X-foobar) into a request
before doing a proxy_pass.

Is there any way to do this without changing the proxy module itself? I
read that there can be only one handler per request. Though my module
retruns NGX_DECLINED after doing its job, it doesn’t seem to get
executed
first and proxy_pass seems to get invoked first.

How do I set dynamic values?
X-Foobar: <some_code_that_looks_at_request_and_generates_a_value>

You module should define a variable. See map and geo modules as
examples.
Then you can use

proxy_set_header X-Foobar $your_variable;
