A form allows a visitor to type information onto a Web page and submit it to your server so you can take appropriate action. You can use a form to request a user’s name and email address, ask them to vote for their favorite item from a list, or allow them to make an on-line order. In each case the visitor provides information and then clicks a Submit button to submit it.

The information is sent to the server, where it is usually processed by a form-processing script. This script typically returns a page to the user’s browser that confirms that the information was received successfully.
To use a form on your Web site you need to provide a script that will handle the information sent back from the completed form. The creation of form-processing scripts is outside the scope of this manual, and if you are publishing your site through an Internet Service Provider you should contact them to see what options are available.
