Starting with HTML 4.0, forms can also submit data in multipart/form-data as defined in RFC 2388 (See also RFC 1867 for an earlier experimental version defined as an extension to HTML 2.0 and mentioned in HTML 3.2). The special case of a POST to the same page that the form belongs to is known as a postback.
Diagram of a double POST problem encountered in user agents. Diagram of the double POST problem above being solved by PRG. Post/Redirect/Get (PRG) is a web development design pattern that lets the page shown after a form submission be reloaded, shared, or bookmarked without ill effects, such as submitting the form another time.
The GET method requests that the target resource transfer a representation of its state. GET requests should only retrieve data and should have no other effect. (This is also true of some other HTTP methods.) [1] For retrieving resources without making changes, GET is preferred over POST, as they can be addressed through a URL.
An HTML browser or other agent can infer the closure for the end of an element from the context and the structural rules defined by the HTML standard. These rules are complex and not widely understood by most HTML authors. The general form of an HTML element is therefore: < tag attribute1 = "value1" attribute2 = "value2" > ''content'' </ tag >.
A user might mistype a URL. Organizations often register these misspelled domains and redirect them to the intended location. This technique is often used to "reserve" other top-level domains (TLD) with the same name, or make it easier for a ".edu" or ".net" site to accommodate users who type ".com".
An early use of CGI scripts was to process forms. In the beginning of HTML, HTML forms typically had an "action" attribute and a button designated as the "submit" button. When the submit button is pushed the URI specified in the "action" attribute would be sent to the server with the data from the form sent as a query string.

The term representational state transfer was introduced and defined in 2000 by computer scientist Roy Fielding in his doctoral dissertation. It means that a server will respond with the representation of a resource (today, it will most often be an HTML, XML or JSON document) and that resource will contain hypermedia links that can be followed to make the state of the system change.
