To close the loop on this, it turns out that one of our cookies did not have a 'Path' specified, causing many duplicate cookies to be created. When we hit the 50 cookie IE limit, IE would delete the oldest cookie - which was our JSESSIONID cookie, causing the user to get logged out.
The reason this did not happen in other browsers was due to much higher cookie limits. Thanks to Willy for the help troubleshooting this. I learned more about browser cookies than I ever wanted to know :) From: Stroehmann, James Sent: Friday, October 7, 2016 2:44 PM To: [email protected] Subject: Issue with windows IE 11 and Edge We have a website that is setup like this: CDN -> HAPROXY -> ELB -> APACHE -> TOMCAT We are seeing with IE11 and Edge clients they will randomly lose their session and get kicked out to a login screen. Firefox, Chrome and older IE clients appear unaffected. Testing at all the different layers, we can reproduce against the HAProxy and CDN layers, but not the ELB/Apache/Tomcat layers, which leads us to believe the problem lies at the HAProxy layer.We are using HA-Proxy version 1.6.3 2015/12/25, compiled from source. I'm not seeing any errors in the haproxy logs, any ideas as to where to start troubleshooting?
