How to get the WCF 4.0 Restful response bandwidth consumed?

Question

Hi everyone,

I have a WCF 4.0 restful application and I need to know the size of the HTTP message before it's sent back to the client.

I have two methods as shown below and both have the token parameter that identify the client. So, when the client calls any method, I need to discover the size of the response and register the bandwidth consumption for that client and method.

Note that the response may return as XML/JSON and compressed either.


Could somebody give me a hand?

	[ServiceContract]
	[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
	[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall, ConcurrencyMode = ConcurrencyMode.Single, Namespace = "")]
	public class ZipCodeService
	{
		[WebGet(UriTemplate = "/GetAddressByZipCode?token={token}&zipcode={zipcode}")]
		public GetAddressByZipCodeContract GetAddressByZipCode(string zipCode, string token)
		{
			// ...
		}

		[WebGet(UriTemplate = "/GetZipCodeByAddress?token={token}&keywords={keywords}")]
		public GetZipCodeByAddressContract GetZipCodeByAddress(string keywords, string token)
		{
			// ...
		}
	}

Any help will be really appreciated.
