Package donottrack is a small helper package for reading the
DoNotTrack flag out of the http.Request.
More Information about the DoNotTrack Header can be found at
https://en.wikipedia.org/wiki/Do_Not_Track
If a user sets the DoNotTrack option inside the browser you
could not render elements, which would track the user.
For example you could not show ads or you could not use
external fonts.
IsSet returns true if a do not track option is set by the
browser in every other case it returns false
If you need more controll over the options you should use
the Request() function.
const (
// OptIn is used, when the user allows tracking OptIn Option = iota// OptOut is used, when no tracking for the user is allowed OptOut
// NotSet if there is no DNT Element inside the header NotSet
)
