// the last 6 tokens. This means that pages are valid for up to 7 hours.
// There is also some Javascript which periodically refreshes the CSRF
// tokens on each page, so theoretically pages should be valid indefinitely.
// However, this code may fail to run (if the user loses their internet
// connection, or there's a JS problem, or they don't have JS enabled).
// Choosing the size of the window in which we accept old CSRF tokens is
// an issue of balancing concerns between security and usability. We could
// choose a very narrow (e.g., 1-hour) window to reduce vulnerability to
// attacks using captured CSRF tokens, but it's also more likely that real
// users will be affected by this, e.g. if they close their laptop for an
// hour, open it back up, and try to submit a form before the CSRF refresh
// can kick in. Since the user experience of submitting a form with expired
// CSRF is often quite bad (you basically lose data, or it's a big pain to
// recover at least) and I believe we gain little additional protection
// by keeping the window very short (the overwhelming value here is in
// preventing blind attacks, and most attacks which can capture CSRF tokens
// can also just capture authentication information [sniffing networks]
// or act as the user [xss]) the 7 hour default seems like a reasonable
// balance. Other major platforms have much longer CSRF token lifetimes,
// like Rails (session duration) and Django (forever), which suggests this
// is a reasonable analysis.
