How can I use a web application on my computer without internet?

Question by Mike: How can I use a web application on my computer without internet?
I want to use a web app even when I don’t have internet access. Can I save the files, and run it through a host program on my computer? Or, if the web host were to send me the necessary files, could I then open them directly in a browser?
Any suggestions would be appreciated.

If you can save the app and run your browser in offline mode it can work. I have some javascript calculators that work offline.
