Setting & Reading Cookies
You can set and read browser cookies from JavaScipt. This is a powerful
technique for storing information that can be used at later time.
Cookie
values are sent to the server with every request. This is why cookie
value length are usually limited. The limitation differes by the browser,
but you can count on 1Kb. You can also set the cokkie for a specific
URL, then it will be sent ot the server only for that URL. Again, there
is a limitation on a number of cookies the browser will save per web
server (domain name). This is to prevent hackers for causing you an
out of disk space condition.
On the
server side cookies can be read from "HTTP_COOKIE" request
parameter. The cookie can also be set by sending a "Set-Cookie:
<value>" header in web server response.
