Are Dynamically Loaded Files Cached by the Browser?

Question

I have a question that is related to this answer, $.getScript(filename)

Are dynamically loaded files cached by the browser?

If not, how can I force them to be?

It seems that they are not. Proposed workaround is to redefine the function:

$.getScript = function(url, callback, cache) {
    $.ajax({
        type: "GET",
        url: url,
        success: callback,
        dataType: "script",
        cache: cache
    });
};

which could be used like this:

$.getScript('/foo.js', function() { }, true);

Thank you for finding this for me. The jQuery documentation for cache (api.jquery.com/jQuery.ajax) says only that if you set cache to false the browser will not cache. It doesn't say that if you set it to true it will cache...off to do some testing

setting cahce: true/false via .ajaxSetup method also affects the getScript.
