POST is one of the HTTP protocol methods; it is used when the client needs to send data to the server as part of the request, such as when uploading a file or submitting a completed form.
In contrast to the GET request method where only a URL and headers are sent to the server, POST requests also include a message body. This allows for arbitrary length data of any type to be sent to the server. A header-field in the POST request usually indicates the message body's Internet media type.
