How to force browsers not to reload recently seen page after resume? When I visit a website then switch to another app, then switch back to the browser the page is reloaded which I have just seen. It happens not just with builtin browser - I also tried Opera Mini and Maxthon.

How can I keep the recently seen page after resuming the browser?
You can't prevent that. If the system (or App) reload the content, this is because it has decided to reload it. There is no option to prevent that.

But you can create your own browser that will handle the resume as you want ;)
