Generate a cookie

 Hi Friends,
 I have to generate a cookie which will contain the username and password which will be captured when a user fills in the values on a web site login page and there is another site  where the values from the cookie will be used to make the user logged in without filling in the values in the second site. I just need the code to generate the cookie on the first web site to capture the username and password. Please provide some sample code.

 
Thanks in advance
Sushim
