Feature request: detect browser prefetch #497

It would be nice to have browser.prefetch? that detects if the request is coming from a Omnibar prefetch that modern browsers perform.

This stackoverflow answer (https://stackoverflow.com/questions/9852257/http-header-to-detect-a-preload-request-by-google-chrome) tells that each browser vendor sends different headers, being:

  • Chrome: Purpose: prefetch
  • Firefox: X-moz: prefetch
  • Safari: X-Purpose: preview

That'd be very helpful.
