Noticed a strange feature.
There are several ad units on the page. We count their number for the cycle. Run the loop. Inside the loop, made $('IDблока').load('ссылкаНаЗагрузкуИзБазы.php'); Omitting the moment that it is not right in the loop to make requests (I am changing already, the decision was temporary) let's go further. 'linkDownloadingFile.php' for each block is the same. The code inside is arranged in such a way that it loads an ad unit with a minimum number of downloads and adds one. Thanks to this, the ads are loaded in all the blocks are different. Ideally.
In fact, this happens on Windows, in all browsers (including the old safari), on the android (in all popular browsers). But on iOS, the site repeats the very first response from php in all blocks. That is, the ads are displayed the same. And not only in Safari, but also in chrome and firefox.
Who thinks what? What could be the reasons?
