Yes the clients connect only directly to nginx. So the proxy config within 2 pairs of containers is like this:
# website service; clientAuth=false nginx:80 -> tomcat:8080 nginx:443 -> tomcat:8443 # API service; clientAuth=true nginx-api:90 -> tomcat-api:8080 nginx-api:5443 -> tomcat-api:8443 nginx and nginx-api ports are exposed to the Docker host and that is where the clients access them, therefore the host name the webapp sees is localhost (as in my rewrite example). What I'm trying to do is to fool the webapp on tomcat-api into thinking it's being accessed on localhost:80/443 instead of localhost:90/5443. Absolute URIs matter in this case because they are used for direct lookups in an RDF triplestore and RDF uses absolute URIs.
