Abstract
A method for communication includes intercepting Domain Name System (DNS) messages that are sent in a communication network in preparation for setting up respective communication sessions that provide respective services associated with respective service types. DNS information that is indicative of the respective service types is extracted from the intercepted DNS messages, and the extracted DNS information is cached. A service type associated with a given communication session is identified using the cached DNS information, and a traffic policy is applied to the given communication session depending on the identified service type.
