Using load() to get data from a parent directory

Using load() to get data from a parent directory

I'm trying to use the ajax load() method to load a file from a parent directory, e.g.

$("#divTests").load("../tests.htm");

But that doesn't work.  I can load a simple html file from the same directory as my html file or a descendant directory, but not an ancestor directory.  Nor can I load from an external server.

Is that just the way it is, or is their a way to accomplish what I'm trying to do?

Thanks for your help.
