You can specify ratings regarding the content of your page. Without a rating it would be possible for some browsers (or programs designed to control what can be viewed) to prevent access to your site. As with all of the < meta > tags, the user will not see the rating, but the browser can process it. If you do provide a rating, the browser is more likely to show it to those who have agreed to view that sort of content.
Initially, Internet ratings were introduced to help parents and schools block certain content from children, although the main technology in this area, PICS (the Platform for Internet Content Selection), has developed to allow lots of other uses.
In order to specify a rating value for a page, the value of the http-equiv attributes needs to be picslabel.
The part that actually indicates what the content is is known as a rating label. The label must be created according to the Internet Content Ratings Association (ICRA).
The rating label is made up of four parts:
- An ICRA identifier
- The ICRA label
- The RSACi identifier (the old name for the ICRA)
- The RSACi ratings
Setting Cookies:
Cookies are small text files that the browser can store on your computer. You can create them in a scripting language that runs in the browser such as JavaScript or using technologies on the server such as ASP.Net, PHP, or JSP.
You are not likely to use cookies until you start working in depth with JavaScript or a server-side language, but they are mentioned here for future reference.
You can use the < meta > element to set cookies by giving the http-equiv attribute a value of set-cookie and then using the content attribute to specify a cookie name, value, and expiration date, like so:
< meta http-equiv=”Set-Cookie” content=”cookie_name=myCookie; expires=”Fri 16 April 2009 23:59:59 GMT” />;
If you do not provide an expiry date, then the cookie will expire when the user shuts his or her browser window.
