I was doing a web trace to see how much my blog would take in loading time, using Chrome Inspector network tools. I then found a video I had posted and decided to click on it.
The weird thing is that while the video was playing (and almost arriving at the end), I saw the following call going to YouTube servers:
Request URL:http://www.youtube.com/set_awesome Request Method:GET Status Code:200 OK ... Query string parameters: : video_id:qqYL53y2mg4 l:12 t:vjVQa1PpcFM6nieoMq9Kt2F5m8ytugSIx-buj-51s6I w:0.857166666666667 ps:default el:embedded feature:youtube_gdata_player plid:AAS2TH2MDq_ZRrI3 eurl:http://blog.alphasmanifesto.com/
(the URL above is my personal blog)
And the answer from Youtube servers was the following:
<?xml version="1.0" encoding="utf-8"?> <ut_response status="ok" />
I do realize (for the data being sent) that possibly this is related to YouTube's video tracking feature, so that people can know when a video stops being insteresting or how much people actually finished sending the video. Is my assumption correct?
