The <FORM> tag's ACTION attribute denotes the destination URL where the form data will be sent. The METHOD attribute has 2 possible values: GET and PUT. When set to GET, the data will be sent as part of the URL (QUERY_STRING environment variable). When set to PUT, data will be sent as a message (the program's STDIN).
The ENCTYPE attribute is the MIME content type the form data is encoded in. It determines how the form data will be sent via the URL or e-mail. The default value when this attribute is not explicitly included is "application/x-www-form-urlencoded".
