Question 209

-- Exhibit --

Refer to the exhibit.

An LTM Specialist has created a virtual server to balance connections to a pool of application servers and offload SSL decryption. Clients connect to the application at https://www.example.com/. The virtual server is configured with a clientssl profile but no serverssl profile. The application servers are listening on ports 80 and 443. Users are unable to connect to the application through the virtual server but are able to connect directly to the application server.

What is the root cause of the error?

The LTM device is chunking responses.
