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?

-- Exhibit -- -- Exhibit -- Refer to the exhibit. An LTM device is used to load balance web content over a secure channel. The developers of the web content have done a trace using an HTTP profiler application. They believe that allowing the LTM device to compress traffic to the client will improve performance. The client can utilize GZIP or deflate compression algorithms. An LTM Specialist must implement the compression. The LTM Specialist has completed the following actions: 1. Create the relevant profile. 2. Apply the relevant profile to the virtual server (VS). After applying the relevant profile, the LTM device is failing to compress the traffic. Instead, the traffic is being served with an error. What is the problem?
