I have a large collection of Windows exe files which are being stored/distributed using Amazon S3. We use signed URLs to control access to the files and this works great except in one case when trying to download a .exe file using Internet Explorer (version 8). It works just fine in Firefox. It also works fine if you don't use a signed URL (but that is not an option).
What happens is that the IE downloader changes the name from 'myfile.exe' to 'myfile' and Windows no longer recognizes it as an executable. Any advice would greatly be appreciated.
