Polymorphic serialization is disclosed. In one embodiment polymorphic serialization may include generating a first reply in response to receiving a first request from a first device, the first reply including first content in a first serialization format. The first reply is transmitted to the first device via a first communication link. A second reply may be generated in response to receiving a second request from a second device, the second reply including second content in a second serialization format. The second reply is transmitted to the second device via a second communication link. The first and second devices are distinct from each other, and the first and second serialization formats are distinct from each other.
