Methods
HTTP 1.1 defines several request methods: GET, HEAD, POST, PUT, DELETE, OPTIONS, and TRACE. Of these, only GET and POST are commonly used in Web applications:
| GET requests are normally used in situations where the user has entered an address into the address or location field of a Web browser, used a bookmark or favorite stored by the browser, or followed a hyperlink within an HTML document.
|
|
| POST requests are normally used when the user has completed an HTML form displayed by the browser and has submitted the form for processing. This request type is most often used with dynamic Web applications, which include business logic for processing the values entered into the form.
