The thing you are looking for is the referrer. This is an optional HTTP
header that most of the times is also made available in javascript via
document.referrer. Keep in mind that this might not be set (or set to the
real referrer, I used to have browser plugin that rewrote all my referrers
to a website of questionable content to mess with the minds of people
reading logs :P)
Read the docs[1] for more info
