Affiliate Cookie Getter

I need a script (php or Javascript). That I can use to load a second page in the background. This second page needs to load without being seen and without loading any images. If it's possible I would like it to strip out everything else that's not related to setting cookies. My goal is to have the second page load while keeping my pages 56k friendly. The second page needs to load either after 5 seconds or after the first page has loaded. For Example: [login to view URL]://[login to view URL] The script needs to be easy for me to use because I really don't know php.
