Good!
I made my own decision for the market. I install the second site. The main page has a slider with a href button. In an infoblock, this property is of type string. The person substitutes url and all. The news list component.

<a href="<?=$arItem['PROPERTIES']['HREF']['VALUE']?>" class="submit"><?=Getmessage('DETAIL');?></a>

The default is "/" and therefore the problem is that when they put the second site on click, it goes to the first site.

How to take into account hard links from banners when multisite? Tell me, I can't figure it out. Or how to do it differently?

Answer 1

It all depends on how multisite is configured.
If on different domains, then there will be no problem.
If by folders, then SITE_DIR solves the problem.
