What the site http://www.youtube.com/lohp is?
When I used the incognito window of Google Chrome to open the YouTube homepage (http://www.youtube.com), the link redirects to http://www.youtube.com/lohp , and the interface of it was changed.
However, when I used the normal window to open the same page, the link was not redirected and the interface has not been changed. The site http://www.youtube.com/lohp was also not found.
What is the use of http://www.youtube.com/lohp ? Is it a test of YouTube interface?
Please help, it is just for curiosity.
