   - Unfortunately, Microsoft has added a clever new
   - "feature" to Internet Explorer. If the text of
   - an error's message is "too small", specifically
   - less than 512 bytes, Internet Explorer returns
   - its own error message. You can turn that off,
   - but it's pretty tricky to find switch called
   - "smart error messages". That means, of course,
   - that short error messages are censored by default.
   - IIS always returns error messages that are long
   - enough to make Internet Explorer happy. The
   - workaround is pretty simple: pad the error
   - message with a big comment like this to push it
   - over the five hundred and twelve bytes minimum.
   - Of course, that's exactly what you're reading
   - right now.
