If content is not present at my site during initial server render, say i use PHP as a server scripting language, the embed is added through Ajax, does this content send my server IP to the content owner? say i'm embedding a YouTube video, does YouTube (let's say they care how many embeds you make) get my server's IP?
Thank you.
AJAX calls are performed by the users browser so yes, they will be coming from the IP adres of the user and not your server.
