Good news: This has been added in release 9.6. To quote the release notes: Virtual Server & Pool Specific SSL/TLS Options Configuration keys have been added to Pool and Virtual Server objects, allowing the listing of the allowed SSL/TLS cipher suites in order of preference and the specification of permitted SSL/TLS versions. By default the globally configured settings are used. The new keys allow the behavior to be overridden for individual Virtual Servers and Pools. The names of the new keys are - 'ssl_ciphers' - 'ssl_support_ssl2' - 'ssl_support_ssl3' - 'ssl_support_tls1' - 'ssl_support_tls1_1' They can be configured from the 'SSL Encryption' and 'SSL Decryption' sections of the Administration UI for each Pool and Virtual Server, respectively, and via the SOAP or REST APIs.
