I used this command line

httrack <http://www.mah.gov.on.ca> -%P0 -v -O "c:/temp/download"
"-*AssetFactory*"

I also tried using different filters (i.e. in place of "-*AssetFactory*", each
on a differnt run of httrack:

"-AssetFactory.aspx*[]"

"-*/AssetFactory.aspx*[]"

"-*AssetFactory.aspx*"

No luck with these, please advise on correct filter, thank you
