Configurable P13N Dynamic Include Behavior

The behavior of P13N Dynamic Includes is now configurable. You can decide to use the container based approach that declares a whole container which contains any p13n relevant content as uncacheable (default behavior, nothing new) or switch to the new approach which will declare single items inside the containers as uncacheable by adding and enabling a new boolean setting p13n-dynamic-include-per-item to the page.

The latter has the advantage that single placements containing a large number of items can still be cached partially if p13n content is contained. Please note that this will only work as expected if you do not use the (now deprecated) getFlattenedItems method of the com.coremedia.blueprint.layout.Container interface. Please also check the corresponding new section "Rendering Container Layouts" of the frontend developer manual for a possible approach to get rid of getFlattenedItems .

Upgrade Notes

The behavior is fully backwards compatible so in case you did not make any adjustments there is nothing to do.

In case you have made modifications to how p13n dynamic include work please note that the constant P13N_DYNAMIC_INCLUDES_SETTING of the class com.coremedia.blueprint.personalization.include.P13NDynamicContainerStrategy has been moved to com.coremedia.blueprint.personalization.include.P13NDynamicIncludeSettings .

In addition to this the existing (but in our default configuration unused) class com.coremedia.blueprint.personalization.include.P13NIncludePredicate now also takes the p13n settings into account. In case you have used the predicate you can decide to add the aforementioned settings to your root channel or preserve the implementation of the version you are migrating from.
