To be clear, this is for a custom http module we wrote. We want it to know about request headers that we set in the nginx.conf (for proxy_pass etc). But it doesn't seem like the custom module receives the modified request headers. Is there any way to both a) set a request header for proxy_pass but also b) have custom http module code living inside the same nginx also process the request that has these alterations to the set of request headers?

Thanks
