Since WebKit 0.6, WebKit uses a modified FieldStorage class that

parses GET parameters even in a POST request. However, the parameter

names must be different. A GET parameters with the same name as a

POST parameter is ignored, these values are not appended. In other words,

POST parameters always override GET parameters with the same name.
