- 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.
