shadow82I have a couple questions that don't seem to have been answered in the rest of the comments.
1. Should this new virtual server only work for https://example.com:8443/services, or example.com with any path, or anything coming in on this new virtual server over 8443 that is https?
2. If you perform SSL termination at the F5 do they want the servers to receive encrypted traffic or the decrypted traffic from the F5?
Depending on your answers you have a few options. You can perform SSL termination without encrypting before you send it to the servers and only balance traffic for specific host and/or URI fields in the host header. Without SSL termination you cannot perform anything based on the HTTP header other than passing it to the server for it to decrypt the traffic.
