 Wouldn't be better to have this kind of functionalities in the QWebView

Got it! So if I don't set a new global network access manager and want to
clear the cache I would need to go page by page clearing them, right?

What is the advantage on having one separated cache for each page? Wouldn't
be better to have one network access manager shared by default? Or maybe a
way to set WebKit to share them.

BTW, Arora is a great reference browser!
