How to create a form that use HTTPS?

Hello!

I need to get some secure cookies from a browser when a user push a button at a form. But how do I tell the form to use HTTPS?

Is this a common solution:

<form action="https://192.168.0.1/int_2/SessionSecureCookies_4d" method="post">

or is should a give the form some other argument?

When I use the above the browser says that it can not create a connection to the server. But perhaps I need to install some certificate at the server?

I use webserver orion 2.0.2 so if any one could give some clues it would be great!

Best regards
Fredrik

BTW
when I set a cookie I do it like:

Cookie cookie2 = new Cookie("int_2_name_secure", (String)form.get("cookie_value"));
cookie2.setMaxAge(10800);
cookie2.setSecure(true);
response.addCookie(cookie2);

Is there some method that can tell me if it is possible to set cookies like isCookiesEnable() ... I have not found any?
