[Apiman-user] Flood of requests to Keycloak when accessing apiman UI

Tue Jan 5 16:05:17 EST 2016

We are testing setting up a configuration where the API gateway, the API manager UI, and Keycloak are all behind their own load balancers on AWS. Keycloak is clustered using JDBC_PING.

When I try to access the apimanui URL after logging in via Keycloak, sometimes the admin page is rendered; sometimes it isn't and I have to refresh it a few times. I see a flood of requests coming into both of the Keycloak instances.

>From what I can see, after the POST to Keycloak happens, there is a sequence of 302 redirects that eventually results in a successful GET to index.html. After that, however, each request for a resource on the page — css, javascript, fonts, whatever — also gets a 302 and is redirected to Keycloak and redirected back before the request is successful. I'm getting the impression from what I'm seeing that the bearer token is not being received by the browser and/or submitted with requests.

Below is an example from the browser request log. All the browser requests are to various subdomains of us-west-2.elb.amazonaws.com (the load balancers); the instances of apiman and Keycloak are all on subdomains of us-west-2.compute.amazonaws.com. There is currently no session affinity set up in the load balancers for Keycloak, the apiman gateway, or the apiman management UI.

Any ideas on what might be causing this?
