How to rewrite the domain part of Set-Cookie in a nginx reverse proxy?
- by Tobia
I have a simple nginx reverse proxy:
server {
server_name external.domain.com;
location / {
proxy_pass http://backend.int/;
}
}
The problem is that Set-Cookie response headers contain ;Domain=backend.int, because the backend does not know it is being reverse proxied.
How can I make nginx rewrite the content of the Set-Cookie response headers, replacing ;Domain=backend.int with ;Domain=external.domain.com?
Passing the Host header unchanged is not an option in this case.
Apache httpd has had this feature for a while, see ProxyPassReverseCookieDomain, but I cannot seem to find a way to do the same in nginx.
