Hello group,

(coss-post from keycloak-user Mailing List)

the undertow servlet-container is started pretty early during the startup of the

wildfly application server. However the initialization of the keycloak server 

application might take a while to complete. Within this period requests that are

sent to the keycloak endpoints result in responses with HTTP Status Code 404.

Is it possible to configure undertow to return a HTTP Status Code 503 (Service Unvailable)

until the keycloak application startup has completed?

This would ease configuring load-balancers and to avoid showing a file not found 

to users during server restarts.

Cheers,

Thomas
