[keycloak-user] Extract kc_locale from a redirect URI

Hi, we are extracting kc_locale parameter from redirect URIs and appending it to the Keycloak login form URI using NGINX rewrite rule at the moment. Extracting locale from redirect URI is indispensable for example when using deep links in emails or linking to protected resources from a public site. I wonder whether there is more simple method to extract kc_locale parameter from redirect URI and set according locale in the Keycloak login form. Best regards, Valerij
