Avoiding Banners Duplication When Using Iframe Delivery

[mx_starter]

Hi, can you pls explain me what is the reason for the option:

Don't show the banner again on the same page

 

to be missing when the delivery method is using iFrames?

 

And is there any way to avoid duplicating banners on a same pages with this delivery tag?

 

Thanks.

Using 2 or more iframes on a single page, these iframes execute independently of each other and in parallel. As such, they are not 'aware' of each other, and therefor it is impossible to prevent the same banner from showing up in multiple iframes.
