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

# Use a single directory to hold cached files.
# (Make sure it is a directory your app has permission to create files.)
mht.put_NumCacheLevels(0)
mht.AddCacheRoot("/Users/chilkat/temp/mhtCache/")

# Tell the MHT component to save files to cache,
# and to retrieve from cache if possible:
mht.put_FetchFromCache(true)
mht.put_UpdateCache(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.
