Hi Remi, Its pretty easy.
1. Create a page that subscribes to the online/offline event. 2 In the handler call a XMLHTTPRequest 3. Leave the browser page open 4. Press the HOME button, go to settings, go to airplane mode 5. Go offline 6. Go Online 7. When you go online it will call yout XMLHTTPRequest Regards, Alon Raskin e: aras...@go3i.com -----Original Message----- From: iphonewebdev@googlegroups.com [mailto:iphonewebdev@googlegroups.com] On Behalf Of Remi Grumeau ?

There is a good chance that LocalDB connection is related / managed by a browser thread.
