Really nice feature :+1:

I also have trouble with this problem. Please fix this asap.

Thank you very much @thomasdarimont - I was not aware of that dedicated attribute.

@MurzNN did you find any workaround?

Thanks, this brought me on the right track. Due to [this change](https://www.keycloak.org/docs/latest/upgrading/index.html#passthrough-proxy-mode-changes) I had to define the `proxy` configuration setting.

> Generate the project locally and then simply copy the 404.html from the language directory under /static/. I guess this will lead to problems as soon as asset URLs will...

@onedrawingperday where do you define this `url` parameter? Does this require creating the `404` page within `content/` explicitly? please elaborate.

Nice solution, thank you.

It seems this is required for making this usable with Symfony 3.4. ``` Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::clearCache PHP Fatal error: Uncaught Matthias\SymfonyServiceDefinitionValidator\Exception\InvalidServiceDefinitionsException: Service definition validation errors (11): - services_resetter: Type-hint "Traversable" requires this...

FYI: I got the update to Symfony 3.4 working with this: https://github.com/zikula/symfony-service-definition-validator/compare/65868c8b0326e09c1f437c9ee1e53a9eb0237e6c...bdafa1be7c80bd8a69d860c7f9d586e61d1fb69e
