provide an option to use the host header for PROXY_REDIRECTION_URL

[cameronbraid]

I wish to use the same proxy instance for multiple domains, which can't be done due to the hard coded PROXY_REDIRECTION_URL env var or command line argument.

Could keycloak support a flag to generate this from the request's host header ?

Yeah .. i recall wanting to make the exact same change, the underlining lib go-oidc doesn't expose the redirection url post client creation though. I've raised a #PR130

[cameronbraid]

ok, thanks

This should be fixed in master branch. If no redirection-url is provided it will use the Host header or the X-Forwarded-Host header .. Let me know if you have any issues :-)
