// public api.

// At the base, though, what we do is a very simple thing to protect
// against CSRF attacks, and that is to simply add another header. If
// HS2 is running with an XSRF filter enabled, then it will reject all
// requests that do not contain this. Thus, we add this in here on the
// client-side. This simple check prevents random other websites from
// redirecting a browser that has login credentials from making a
// request to HS2 on their behalf.
