Dispatcher cache not invalidated

Symptoms

After having updated some images on the homepage, the media library page and homepage were activated. The publish instance was updated but not the dispatcher cache.

Cause

The dispatcher flush configuration was incorrect.

Resolution

In general the publish instance is installed directly under the root folder. However, in case it runs under another web app path, the dispatcher flush configuration must be adapted; for example if the publish instance runs under /publish :

<header name="CQ-Handle" value="{external-handle}" />

it must be modified to

<header name="CQ-Handle" value="/publish{external-handle}" />
