See 'Service' box on the right of the diagram. The correct text for the 200 status code should be 'OK' instead of 'Created'.

Example 2-2

Great work in explaining REST in the first chapters. I found only one minor omission in preparing the reader for configuring up WCF to use a host such as Internet Information Services (IIS). When the reader runs the first sample they would get the error: HTTP could not register URL http://+:8889/TestHttp/. Your process does not have access rights to this namespace (see http://go.microsoft.com/fwlink/?LinkId=70353 for details). The solution is explained on the Microsoft link. But I thought it would be nice to prepare the reader for this error so that to avoid any interruption in their experience.

Code sample 11-17

The code in example 11-17 has a serious bug. The ETag created isn't quoted (as required by the specification) this may cause problems with certain clients. The code should look like this: string GenerateETag(User u) { byte[] bytes = Encoding.UTF8.GetBytes(u.UserId + u.LastModified.ToString()); byte[] hash = MD5.Create().ComputeHash(bytes); string etag = Convert.ToBase64String(hash); return string.Format("\"{0}\"", etag); }
