Hi guys,

I use the following code to save a uploaded file on server:



If the file uploaded by Firefox, the fileName contains only file name.
If the file uploaded by IE, the fileName contains absolute path on client's computer which may exposes security threat.

So why's the different?

That is a security bug in IE.

I tested with IE 6, maybe the later version fixes the bug.
