Re: Question about SC 1.4.2 - can this be met by relying on Windows (or otherwise the platform or user agent) to do it for you?

Would it not be sufficient to be in an environment where one has access to,
but is not limited to windows 7? We have considered techniques that have
support only in certain browsers, especially the infamous "headers
technique" relying on a plugin. With regard to web technology I believe we
have said in the meetings that support for a certain technique does not
have to be across the board. Is an operating system different in this
regard?
