For example, in Multix the browser can issue a crafting request for page contents

The fact the HTML might sit on a remote server is a crafting detail left to the categorical machine

I have some examples on Twitter

The server in turn may need to issue crafting requests to load stuff from disk

The nice thing about crafting is that stuff gets cached in inventory as a side effect. You can toss inventory as a way to clear the cache
