| * the request could be expressed like this:</p> |
| * |
| * <pre> |
| * |
| * def request = [ |
| * path : "a/path", |
| * method : "GET", |
| * query : [ |
| * parm1 : "1", |

| * header2 : "more_stuff", |
| * ] |
| * contentType : "application/json", |
| * body : '{"location" : "home" }', |
| * ] |
| * </pre> |
| * |
| * <p>The adapter will translate this request into calls specific to a particular HTTP client.</p> |
| * |
| * <p>The response is then returned with POJOs with this structure:</p> |
| * |
| * <pre> |
| * |
| * def response = [ |
| * status : 200, |
| * headers : [ |
| * header1 : "response_stuff", |
