Hello @spahrson!
Thanks for this PR, it seems to be a great addition! I don't know keycloak, can you tell me a little bit about it? What is your usage of keycloak for example?
I will discuss about it with the team and I will come back to you before the end of the week 🙂 But it should be ok!

Hi @curquiza.

Keycloak is a open source identity and access management solution. It can act as an OAuth 2.0 and OpenID connect compliant authorization server and there is a proxy called Gatekeeper to protect non-oauth compliant applications. We use Keycloak as Single-Sign-on solution. We use antora for documentation and meilisearch to search our documentation. Our antora instances are protected by Keycloak. So we need the ability to scrape antora for meilisearch using an OAuth 2.0 Bearer-Token. This PR fullfills this requirement for Keycloak.
