Hello

I have taken the NGINX training but the following question was not covered. I am hoping I can get some help from the community. Thank you in advance.

Can NGINX add empty (or static non empty) payload to a request when proxying to a server in the Location directive (or elsewhere)

For example

Client => NGINX => Server

Client sends http://example.com/some/path
NGINX adds -d '{"version": "1.1"}' -H "Content-Type: application/json"
Server receives http://example.com/some/path -d '{"version": "1.1"}' -H "Content-Type: application/json"

The reason why I am asking is because I have a client that sends requests without payload and the server expects that payload exists (even if it does not get processed)

Thank you for your help
