When I choose an URL, from the Favorites(Bookmarks) in a browser, to be
downloaded, what happens is that the browser is starting to download
the URL, but only after a while the URL is displayed in the Address
bar, while the URL is still downloading.( this can not be observed in
case the URL is downloaded very fast)

I don't know exactly what this means but what I wonder is: can the URL
be cached by an app( and displayed in a Text Box for instance) before
it is completely downloaded and displayed in the address bar in the
The browser is sending the request towards a server and I wonder if the
URL can be cached while the browser is sending it.

What do you think?

Thanks in advance
