anchor.diff:  specifies the GET method, but it will be set automatically for you if you omit it:
   *)
   
  -Http.Request("http://httpbin.org/get", query=["test", "foo"], meth="GET")
  +Http.RequestString("http://httpbin.org/get", query=["test", "foo"], meth="GET")

  Http.Request("http://httpbin.org/post", bodyValues=["test", "foo"])
