You wouldn't because you wouldn't store a password in a cookie.
If you are implementing a log in system, a user's password should be stored, hashed, on the server.

Wrong method for handling a password, if you keep a password in a cookie any time it got erased or intercepted in some way, don't do that. MWinter is 100% correct.
ASP
In ASP The "Response.Cookies" command is used to create cookies
The "Request.Cookies" command is used to retrieve a cookie value.
Writing a cookie, cookie name is user and cookie value is codeexploiter
Reading a cookieCode:<% Response.Cookies("user")="codeexploiter" %>
Cookie with keys: creationCode:<% username=Request.Cookies("user") response.write("user name is " & username) %>
CODE]Response.Cookies("user")("fname")="Code"
Response.Cookies("user")("lname")="Exploiter"
Response.Cookies("user")("country")="India"
Response.Cookies("user")("age")="25"[/CODE]
Cookie with keys: reading
Code:Response.write Request.cookies("user")("firstname") Response.write Request.cookies("user")("lname") Response.write Request.cookies("user")("country") Response.write Request.cookies("user")("age")
If you want to learn how to set cookie using PHP then check the following
The setcookie() function is used to set a cookie.
Note: The setcookie() function must appear BEFORE the <html> tag.
Syntax
setcookie(name, value, expire, path, domain);
PHP Code:<?php
setcookie("user", "codeexploiter", time()+3600);
?>
Retrieve a Cookie Value
The PHP $_COOKIE variable is used to retrieve a cookie value.
In the example below, we retrieve the value of the cookie named "user" and display it on a page:
Here we check whether a cookies exist/has a value or notPHP Code:<?php// Print a cookieecho $_COOKIE["user"];// A way to view all cookies
print_r($_COOKIE);
?>
If you want more details about this topic then refer PHP manualPHP Code:<?php
if (isset($_COOKIE["user"]))
echo "Welcome " . $_COOKIE["user"] . "!<br />";
else
echo "Welcome guest!<br />";
?>
