4.7.2 Parsing HTML

Forms are the currently the commonest approach to making requests with parameters. These are encapsulated in the <form> tag, with the various parameters as part of the <input> or <select> tags. When the system uses the GET method, these are concatenated on the end of the url as name=value pairs, encoded to escape characters as necessary, and separated by &.

When the url uses the post method, then the parameters are passed as input to the request, again encoded as name=value pairs, encoded to escape characters as necessary, and separated by &.
