Downloading client content and Content Distribution integration

1E Client downloads content from the 1E Background Channel. Content is mainly scripts and other files required by instructions. It also includes client resources such as extensible modules, providers, and other dependencies to maintain the 1E Client. In most cases, client resources are version controlled to prevent repeated downloads. 1E instructions always request a download even if they have run an instruction before, unless the content for that instruction has been cached in memory.

You may need to consider the impact on the network if there is a large amount of content included in an instruction. This is more of an operational consideration instead of a design consideration.
