That's correct, but it's the server's OS that's important, not the client's.

That's OK. It's more than reliable enough. > There are other browsers and bots that have MSIE > in their user-agent header. I hadn't considered bots. Is that of any concern? If so, please explain what I'm missing. Isn't sending 400, 403, etc. status codes to *some* bots better than sending them to none? Put another way, bots that don't send "MSIE[space][digit]" in their user agent string would get customizable "400 Bad Request" and "403 Forbidden" responses, when appropriate. Bots that do have "MSIE[space][digit]" get the same, slightly inappropriate "200 OK" as now. No harm done. Which non-IE browsers have "MSIE[space][digit]" in their user agent string? I'm not sure that even matters. The issue is the same with browsers as with bots. It would be better to send a Site.Error403 page at least sometimes. It's a way to enhance the visitor's experience and communicate more accurately with bots with almost no adverse effect compared to the alternative.
