No. The server does. With IE this is even a bug:
If the server sets a pragma: No-cache header, IE refuses to store the thing at all. Even if it calls another program to display the (non-existing) file.
Such headers are sent to prevent caching, not to prevent the browser to call a plug-in.

I have just do this test:
deleted all in Temporary Internet Files,
run a html file with content
<html>
test
</html>
goto Temporary Internet Files and found nothing in the file table.
I don't know why. But I can imagine that not all files will be cached. It is probably fast enough to re-get such a file instead of caching it. If you want to know why the .swf files are missing, IE7 can be equipped with some plugin that shows the page headers. You may have to install some logging http proxy to do that.

What I thought is any thing must be downloaded and saved into somewhere in my hard disk before/after being displayed in the browser......If this is incorrect, do you know what types of files will be saved?
