D.6. Checksum property resolver
Syntax
The checksum property resolver can be used, if you want a resource to reload automatically at run time, whenever it is updated. The
checksum: scheme can be prefixed to any of the usual location URL handlers (for example, file:, http:, profile:, zk:).
For example, the
default profile defines the following checksum property in the org.ops4j.pax.web PID:
org.ops4j.pax.web.config.checksum=${checksum:profile\:jetty.xml}
