Remixing for Cache

I have a web thing. I did the server end stuff in Perl and right now adding some UI usefulness stuff with Javascript. I'm doing this using Chrome as my #1 browser, under Windows 7 64-bit, and I'm finding a problem.

Specifically, I make changes in the .js file and can't get Chrome to load the changes. I know that I can get that with CTRL SHIFT DEL , but with Firefox, if you hit CTRL SHIFT R on Firefox (and I think IE, but I've never been a big IE user so I'm not sure), and I somewhat recall that behavior as something Chrome did but no longer does.

Anyway, GRRR.
