Fetching Files From Remote Server Using LCS Actions

Prior to ESc Release 4.0, a file locator is added to the LCS action scripts to fetch external configuration files. The file locator contains a reference to the file server, and the relative path to the file to be downloaded. Starting from ESC Release 4.0, the file locator attribute is defined at the deployment level, that is, directly under the deployment container instead of policy actions and day 0 configuration sections.
