}
return null;

1. How to delete the cookie on specific page, the above which has been created ?

2. When does this expire ? I want it to expire after minutes.


Please help me with this... really grateful to you.

 

Use this code to set expiring time by minutes:

if you set 0 the cookie is trashed when the user closes the browser ex: createCookie('doRedirect','true','0');
