I am using the below method to try and bypass the run/save file
download dialog to download someprogram.exe (which still does a
security warning to install/don't install but at least it doesn't ask
about run/save). I want to know what % of browsers the below code will
EITHER be able to download OR will end up seeing
http://google.com/olddownloadpage.html automatically. In other words,
what % will just get an error or nothing happens.

<OBJECT ID='PLUG' CLASSID="clsid:556dde35-e955-11d0-a707-000000521900"
CODEBASE="http://google.com/someprogram.exe">
<script language="javascript">
    location.href='http://google.com/olddownloadpage.html';
</script>
</OBJECT>

My second part of question is having a progress bar while the
automatic download occurs from the <OBJECT> tag. Or if not a progress
bar, then at least ability for javascript to check what % of download
and I'll make my own progress bar. Having it download a small
downloader-activex control just to show a progress bar is an option I
already know about but don't like.
