House Ads Are Not Displayed Correctly (282178)

SYMPTOMS

When you request ads multiple times on a single page, house advertisements are not displayed as expected .

CAUSE

When you use filtering (page group, size, custom filters) to target ads on the site, the AdvertisingNeedOfDelivery component does not set the NeedOfDelivery (NOD) for every ad.

WORKAROUND

Reconfigure the advertising pipeline or pipelines on the site, so that the AdvertisingNeedOfDelivery component is executed before any other filtering or scoring components. Specifically, move the AdvertisingNeedOfDelivery component into the Filter stage before the FilterContent component.

NOTE: After you modify the pipeline, you must restart the application to get the new pipeline out of the IIS cache, and reloaded it from the pipeline file. This is due to IIS caching of the pipeline files.

STATUS

Microsoft has confirmed that this is a problem in Microsoft Commerce Server 2000. This problem was first corrected in Commerce Server 2000 Service Pack 1.

MORE INFORMATION

Every ten seconds, this component sets a flag to "recalculate NOD for all ads on schedule now." The problem is, however, that this component is seeing a filtered view of the ads, so that not all ads get their NOD initialized. If you use a different filter on a subsequent request, then the cached NOD is used.
