- marcosdumay 4y agoIt's probably requesting the pixel. All the info is on the request data. This is a very common pattern.
- kristjansson 4y agoPixel is just a term of art. Facebook (or whomever) have their JavaScript on the page, which sends information back. Historically, this would be a GET request for a 1x1 image, with all the information of interest packed into query params on the request. Hence, the “pixel” colloquialism.
