Downloads a web page into a .mht web archive. Embedded images and style sheets are loaded and/or saved to a disk cache. Lua

local chilkat = require("chilkat")

-- This example assumes the Chilkat API to have been previously unlocked.
-- See Global Unlock Sample for sample code.

local mht = chilkat.Mht.new()

-- Use a single directory to hold cached files.
-- (Make sure it is a directory your app has permission to create files.)
mht.num_cache_levels = 0
mht:add_cache_root("/Users/chilkat/temp/mhtCache/")

-- Tell the MHT component to save files to cache,
-- and to retrieve from cache if possible:
mht.fetch_from_cache = true
mht.update_cache = true

-- The 1st time this is run, the parts (image files,
-- style sheets, etc.) will be saved to the disk cache.
-- The 2nd time this is run, the parts will load from cache.
-- Note: The main content (i.e. the HTML page)
-- is not saved to cache, nor is it retrieved from cache.
-- It is only the sub-parts (embedded images, style sheets)
-- that are saved to and loaded from cache.
