 * Thanks a lot for this good hint, I made some experiments with turning on/off 
   Comet Cache and I see the same problematic behavior when AO ist disabled when
   I delete the Comet Cache.
 * Then as I disabled Comet Cache and enabled AO I didn‘t get a referrer at all,
   even in the >= 2nd page calls.
 * But now I found a solution which seems to work at first glance:
    I added this
   code to .htaccess: Header set Referrer-Policy “origin”

 * Interesting hint. Do you mean with „page cache“ the browser cache? Or some kind
   of cache within wordpress?

 * Ok, thanks for the quick answer. The strange thing is that when I deactive the
   whole AO plugin, I see the referrer in the first call after that and everything
   works fine.
 * This plus that I see the problem only after cache deletion leads to my conclusion
   that (maybe?!) it has something to do with AO.
 * From the vimeo support I got the general hint to check whether there is anything
   blocking the referrer.
