I have a small ad network. Its invocation codes are iframe.
The issue is that, if the publisher pastes the ad code more than one place in the same page, then there is issue with opera.
Opera loads the first iframe from the server, then loads others from cache, So all ad boxes shows the same ads.
However other browser are fine.
In Chrome, IE and FireFox, there is no problem. They show different ads in each box.
Please open this page with opera and other browsers to see the difference.
How can i prevent this opera iframe caching ?
