When creating a policy to allow specific applications, you must also be sure that you are allowing any other applications on which the application depends. In many cases, you do not have to explicitly allow access to the dependent applications in order for the traffic to flow because the firewall is able to determine the dependencies and allow them implicitly. This implicit support also applies to custom applications that are based on HTTP, SSL, MS-RPC, or RTSP. Applications for which the firewall cannot determine dependent applications on time will require that you explicitly allow the dependent applications when defining your policies. You can determine application dependencies in Applipedia.
The following table lists the applications for which the firewall has implicit support (as of Content Update 595).
