Hello,
I've been reading this thread and it remembered me a similar case (I don't
know if it really classifies as a bug, so I haven't reported it).
Once I had to embed a non-secure object coming from another server to my
secure page (only available over https), then i did the following: i wrote a
simple redirect script like this
<?php
header("Location:".$url);
?>
and on the real page asked object through that script like this
<img src="redirect.php?url=http://non.secure.server">
Both IE and Mozilla displayed this object without any warning.
