Internet Explorer Cannot Download https://something (Eric Law’s IE Internals)

Earlier today, I was asked to troubleshoot a secure site where file downloads were always failing. Having seen this problem many times often over the years, I immediately suspected that the web developer wasn’t aware that

if a user tries to download* a file over a HTTPS connection, any response headers that prevent caching will cause the file download process to fail.

When Internet Explorer encounters a HTTPS download that will not be cached, the download is aborted with the following dialog box:

Native boot from VHD on a Windows XP computer (Mark Wilson blog)

Like almost every other corporate in the world, where Mark and I work there is a standard build deployed to everyone. The default in our particular organisation is a 32-bit Windows XP OS regardless of the capabilities of the laptop or desktop it is deployed to. Over the years, this has caused a number of problems that have required an increasing number of “exemptions” from standard policy to allow people to run a different Windows version or platform.
