I think I get the basic concept of calling redirects to various sites from the page, probably back-end like with php, CURL maybe?
I just don't get how you'd keep track of where it goes after the redirect (trying a link) since you would now be on Facebook's site for example
- proaralyst 10y agoThere's an explanation further down the page, but essentially the redirect they choose is an image. You can tell if an image loaded successfully using JS, so if the redirect succeeds, that JS fires. If it fails (because the login page isn't an image), some other JS runs instead.
- ge96 10y agoOh okay, that makes sense. It's like those tracking/analytics where they know where a person came from previously to follow their "thought pattern" that is something I'm not 100% in either.
