How can I prime the Pentaho Report cache using PDI?

Hello,

I'm not sure if I should ask this here or in another sub-forum.

I want to prime the Pentaho Report cache. I have tried using a HTTP client in PDI with the URL (http://localhost:8080/pentaho/api/re...ba.prpt/viewer). I get a 200 status code and a html page as result, but the report is not executed and the cache isn't primed.

How can I do this?

Thanks.
