Strange Issue with ACE Cookie Stickiness - HTTP 503 Service Unavailable
I have configured cookie based stickiness on a serverfarm with two nodes. I have noticed that only 'few' pages on our web site experiences a hang (blank white page/HTTP 503 - Service Unavailable) due to enabling the cookies. The stickiness continues to work properly though.
However, if I were to disable cookies and enable source IP based stickiness, the whole web site runs perfectly without any issues.
I have also checked the release notes to see if similar bugs have been reported. Please advise what could be the reason for this strange issue and how could it be fixed.
Re: Strange Issue with ACE Cookie Stickiness - HTTP 503 Service
Have you taken a look at the webserver log? Any chance the presence of the ACE-generated cookie presents a problem at the webserver?
I would probably run a trace to see what actually happens when this error occurs. Also, try'n take a look at the http-stats on the ACE, 'show stat http', and see if ACE reports an unexpected level of errors. I've experienced issues with abnormal session termination, simply because the http-header exceeded the default header-length, that ACE permits.
