We are storing the Resourcebundle in the HIPPO CMS, and publish it through REST API, using the library plugin option.
Now to enable REST api client caching, the REST response header received need to have
following header entries.
We are able add the header entries through
hst:responseheaders @ path /hst:hst/hst:hosts/dev-localhost/localhost
But how can set the Last-Modified header with value of the variable/node jcr:lastModified ?
