Severity: 3-Major


Portal Access uses special HTTP request with URL '/private/fm/volatile.html' to exchange cookie data between client and BIG-IP. Sometimes the BIG-IP system might send an invalid response to such a request. As a result, no cookie data can be sent from the backend server to the client.


Portal Access client cannot see cookies set by the backend server. Backend server does not send cookie data to the client.


Invalid response to HTTP requests with the following URL: /private/fm/volatile.html.



Fix Information

Portal Access now sends correct HTTP responses with backend cookie data to the client.
