We have a Local Director 417 with 4 servers behind it. We require stateful SSL sessions for our web application that runs on our web servers. Currently we are using Generic SSL, but a vast majority of our clients are sitting behind Server Load Balancing Proxies. Thus, their IP addresses have a tendency to change and cause their session to terminate.
As an alternative, we decided to use the Sticky SSL. However, upon testing we cannot get this to work at all when the client connects through a proxy. From the LD's point of view, I can see an SSL Proxy connection being initiated (show conns), but running traces from the servers shows no communication b/w the LD and the server for that session. Eventually the connection times out. From the client's point of view, I can see a connection to the proxy being established, but eventually a "HTTP 1.0 500 error from proxy" is returned.
One other scenario I tested was to bypass the local proxy. When I do this, the connection is established and the SSL Sticky seems to work fine. However, I cannot expect the clients to "bypass" their proxy in order to gain access to our web apps.
Capturing b/w these 2 devices is the one piece I don't have. It would require the assistance of another group in our environment...not an easy task, but I agree it's something that will need to be done to see exactly what is going on.
I have not setup any sort of route within the LD.
Software version is 4.2.5 (latest version).
Question: Would the Cisco CSS Switch resolve the problem we are currently seeing with session states being dropped when using Generic Sticky?
