A virtual server has been configured for SSL offload on a single-arm network. On average, the virtual server will be handling 100,000 connections, with a peak of 130,000 connections. Between the virtual server and the web servers there is a single reverse proxy to provide site caching. The proxy is configured to perform source IP persistence before contacting the web servers. The site is logging users out immediately after logging them in.
What should the LTM Specialist do to resolve this issue?

After upgrading LTM from v10 to v11, users are unable to connect to an application. The virtual server is using a client SSL profile for re-terminating SSL for payload inspection, but a server SSL profile is being used to re-encrypt the request.
A client side ssldump did NOT show any differences between the traffic going directly to the server and the traffic being processed by the LTM device. However, packet capture was done on the server, and differences were noted.
Which modification will allow the LTM device to process the traffic correctly?
