My cached data is pulled from the imdb list files, it does not create an online database, is not a commercial application, it's not charging any fees, It does reference IMDB as the source of that data with links to there site.
MIP's cached data is in compliance with the imdb list file usage.
Quote:All data and software released by Internet Movie Database Ltd is
freely available to anyone within certain limitations. You are
encouraged to quote subsets of the database in USENET articles,
movie related FAQs, magazine articles etc. We do ask, however,
that you make reference to the source of the data and provide a
pointer to the database for the benefit of the reader.
MIP also does a standard http query and downloads the same full html page as any other browser, the difference is in how I display that data as I parse it into a different format again with reference to IMDB as the source of that data.
