Thread Name: Tech: How Fakebook follows you around
Subject: RE: Tech: How Fakebook follows you around
When you copy a link from FB it often has a mass of gibberish starting with "fbclid=". - fb & id are obvious but cl (clone?)
Well, the gibberish is part of it but I am referring to how they can (?) with simple websites just place it in a FRAME so the top.document is theirs. Or even a modified clone of my page!
The fact that my document.location.replace(u); causes problems tells me that in a new window - ostensibly separate from Fakebook - for my simple JavaScript line to cause a problemo - there has to be another script lurking that I didn't put there! There may be a clue in that I put the script in the <HEAD> not the <BODY> (I stop digging when I reach a result).
the (u) above is computed text (from the subdomain) to decide which target page the URL implies. eg lcms.mister.red > lcms.mister.red/lcms.htm , it then jumps to the target page - Making for a shorter more memorable URL, ie Lancaster Canal MileStones
FWIW the external link on Wiki (LC page) has no snooping frippery.
