A web browser communicates with the server typically using one of the two HTTP methods, GET and POST.
Both methods pass the information differently and have different advantages and disadvantages.
When the method is POST, form data appears within the message body of the HTTP request instead of the URL.
POST method should always be used when sending passwords, SQL Query Strings or other sensitive information.
POST requests cannot be bookmarked
POST requests cannot be distributed & shared
When you click on the submit button, notice the values are NOT part of the URL.
