There was a security camera with a built-in HTTP server at a previous job. The built-in server would respond without a problem when viewed from one computer, but would force close the connection without a response when viewed from another computer. I used Fiddler to compare the requests from the two computers and eventually discovered that the request would fail if the `Accept` header was longer than some value (might have been 255 characters -- I don't remember). Turns out when you install Microsoft Visio and Project, Internet Explorer's Accept header gets really long.
