Preloading support in browser
Apps like the QSB can request the browser to preload a
web page.
- preloaded pages are not added to the browser history
if they'r not seen by the user
- when a request is received, a new tab is created for the
preloaded page, but not added to the tab list
- upon receiving the view intent for the preloaded page
the tab is added to the tab list, and shown
- if several pages are preloaded consecutively in the same tab,
the back stack is cleared before it is displayed
- preloaded pages use the main browser cookie jar, so pages that
have never been viewed by the user can drop cookies
