I have client on localhost on port 8080 lets call it A. I have a backend API on localhost on port 3002 lets call it C. A doesn't connect to C directly, but via a secure tunnel with HTTPS, lets call it B. So the process is like this:

A: http://localhost:8080 =>
B: https://localtunnel.me/some-id =>
C: http://localhost:3002

The problem is that if A configures withCredentials: true, the httpOnly cookies won't be pass through the proxy - it would only work if A was talking directly with C.

How to make it work, or that I am doing something wrong.
