Canvas banner html5 and demdex URL

Good morning. I use from years Animate mainly to create html5 adv banner.

Today I receive a complain from a client that says that there are some problems to upload my banners on the adv server since in the html5 there is a URL call not required and not approved: "domaniclientname.demdex."

In the html5 and in the .js I did't find this call. I fond that this "demdex" it's like an automatic third-part call to adobe audience. Is it possible to eliminate this or find a workaround to solve this out?

Does anyone knows something about this?

I think this could be a big problem since the browser will not accept anymore third-part calls, isn't it?

Thank you.

Stefano
