I have an existing v3 ServiceStack implementation and I want to change the way in which the dates are serialized/deserialized. However, since there are a large number of existing external customers using this service I can't just make that change globally without breaking their mobile applications that use my services.
As a result I want to change the JsConfig<DateTime>.SerializeFn but only when a particular request header is identified.
How would I go about this per request, rather than at the application level?
