We are using wildcard certificate in F5 (for eg: *.lab.com") & ssl offloading web applcation (for eg: "a.lab.com") on this client ssl wild card certificate.
Just want to check we have a new application requirement to ssl offload ( for eg: "a.test.lab.com" ) - can i use the same wildcard certificate (*.lab.com") for ssl offloading of "a.test.lab.com" - will it work.
Wildcard domain ssl certificate includes first level subdomain. Does not include a.test.lab.com or www.test.lab.com. You need *.test.lab.com wildcard ssl certificate or multilevel wildcard ssl certificate for second level subdomain.
