Hi All,

I forgot to mention that I also updated our load balancer to do cookie and source ip session persistence.

Subject: [External]IDP v3.4 Duo Stale Requests

Hi All,

I am running clustered IDP servers behind a load-balancer. Session information is shared across IDPs using Memcache.  My Shibboleth IDPs are v3.4.4.  We recently rolled out Duo and have had an increase in Stale Requests.  I have combed through the archives trying to find possible solutions.  What I have been able to identify is that the Stale Requests seem to be happening when users do Push authentications.  Based on previous posts I have added the JSESSIONID to the logs to verify the session isn’t getting lost.  I have had users try across different browsers and platforms.  I have confirmed by screensharing with my users that they are not hitting the back button or using a shortcut. In some instances I have been able to have the user open a private browser/incognito window and have had inconsistent success replicating the issue.  I am seeing the following in my logs:
