    The GET method requests transfer of a current selected representation for the target resource. GET is the primary mechanism of information retrieval and the focus of almost all performance optimizations. Hence, when people speak of retrieving some identifiable information via HTTP, they are generally referring to making a GET request.
    \nA payload within a GET request message has no defined semantics; sending a payload body on a GET request might cause some existing implementations to reject the request.<\/p><\/blockquote>\n

    The POST method requests that the target resource process the representation enclosed in the request according to the resource\u2019s own specific semantics.<\/p><\/blockquote>\n
