x-request-guid

Optional caller-specified request ID in the form of a GUID. The idea of the X-Request-Guid is that a client can create some random ID and pass it to the server. The server then include that ID in every log statement that it creates. If a client receives an error it can include the ID in a bug report allowing the server operator to look up the corresponding log statements (without having to rely on timestamps IPs etc).
