Hi,     I am using nginx as the reverse proxy in front of  a keycloak and a web application .        Here is a snippet from nginx    location   /foo/bar/   {           proxy_pass   http://127.0.0.1/hello/world/   }     I select the client type in keycloak to "confidential"  so there will be a redict URL  will return back to browser,    will may look like   127.0.0.1/hello/world . Obviously  It failed  .   Is there solution ? Thanks in advance.   Mai
