Publishing CRL and CRT files automatically to a web server

Hi, when you configure the Extensions on an Enterprise CA and specify a URL to a web server for the CRL and CRT files - How does one schedule this to happened for example, every week? or do I need to create a script that will copy the new files every week to the virtual directory on my web server?

For my test deployment I have set CRL to 1 week, with 2 days of Grace period, and set the CRL Delta to 1 day - so would I create a script and schedule a task that would copy the newly published crl file every 7 days? and the delta file every day?
