• This method appends the form-data to the URL in name/value pairs
• This method is useful for form submissions where a user want to bookmark the result
• There is a limit to how much data you can place in a URL (varies between browsers), therefore, you cannot be sure that all of the form-data will be correctly transferred
• Never use the "get" method to pass sensitive information! (password or other sensitive information will be visible in the browser's address bar)

Notes on the "post" method:

• This method sends the form-data as an HTTP post transaction
• Form submissions with the "post" method cannot be bookmarked
• The "post" method is more robust and secure than "get", and "post" does not have size limitations
