Description

Please add support for X-Forwarded-Prefix header. This can be used in cases in which the context-path of the reverse proxy differs from keycloaks context-path:

apache2:  https://apache2/keycloak
keycloak: https://keycloak/

which would require the reverse proxy to pass the information about the context-path "/keycloak" to the server

spring for instance does solve this problem by setting the following two configuration params:

# used to resolve the headers:  X-Forwarded-Server, X-Forwarded-Proto, X-Forwarded-Port
server.use-forward-headers=true

# used to resolve the header: X-Forwarded-Prefix
server.forward-headers-strategy=framework
