How to make a AJAX request while a tab is not open

Question

I am working on offline app for chrome and wondering if there is any way to sync data that is queued up while offline and sync back in when I go back to online even without needing to keep the tab open.

Offline Gmail App for Chrome does that. when I send an email while offline and close the tab, then when I get back to online this email is sent. I would like to know if there is any chrome extension or some sort to accomplish this task.

any suggestions are welcome. thanks

Use a background.html page. In it you can run any JavaScript that you want and have it sync data silently in the background.
