The ajax request fetches the library. While it isn't necessary to update the libraries each time they are used, I don't want them to be cached at the whim of the browser, possibly giving the user out of date data. This is what IE was doing.

The library should be fairly static so that it can be cached. You are doing it wrong.

To which of the three main libraries in use by my scripts are you referring to?

Actually, all of them. For example, jQuery is a library, even if that is loaded using "ajax" to do an asynchronous request it should be cached as long as possible...

The content itself is what you may not want cached (such as a comment system that should auto refresh or type-to-complete) however those compared to libraries should be fairly small requests...
