In the Advanced tab of the Zone properties page, you can set the following properties:

Zone chaining

It can occur that a zone cannot display an ad because it is not linked to any active banners or because delivery limitations prevent it. To stop this happening, you can create a chain of zones. In a chain of zones, if it is not possible to display a banner for the zone, a banner from another zone can be used.

If you select Stop delivery and don't show a banner, an empty space appears on the website if no banners can be displayed for this zone.

If you select Display the selected zone instead and select a zone from the drop-down menu, OpenX will display a banner from that zone if no banners can be displayed for this zone.

Note: Only zones from the same publisher are available in the menu unless you made zones for another publisher public.

Delivery capping of zones

You can place a cap (or limit) on the number of times a visitor sees a zone. You can cap zones in two ways:

  • To cap the total number of times a visitor sees the banners linked to this zone, enter the number in the Limit zone views to: total field.
  • To cap the number of times a visitor sees banners in this zone in a single session, enter the number in the Limit zone views to: per session field.

OpenX records the number of views in cookies and you can reset the cookie after a specified period by setting it in the Reset view counters after: field. If a visitor has disabled cookies, banners in capped zones will not be delivered to that viewer. If a visitor deletes existing cookies, the cookie is reset to zero and the visitor will see banners in this zone until the limits are again reached.

Zone append

You can generate additional HTML when a banner is delivered for a zone, for example to show another form of banner, such as a pop-up. This code is executed each time a banner from this zone is delivered. You can enter your own HTML code or paste code from a supported ad network.

For text ad zones, you can prepend and append HTML to the text ad to determine the layout of the ad.

If you set the Append even if no banner is delivered option to 'Yes', the additional code is delivered even when no banner is delivered.
