I'm programming an applet and testing it with IE 5.5.
I have Tools | Internet Options... | General (tab); Temporary Internet files | Settings... | Check for newer versions of stored pages: Every visit to the page selected;
and I even Delete Files...
Tools | Internet Options... | General (tab); Temporary Internet files | Delete Files... (but not all offline content).

I even set an html refresh meta tag (which I suppose only automates the refresh button)

Do I have to do something special to make sure I reload the newest applet class file?
