The browser support is a bit flaky as I understand it, from the numerous caching problems with pages across browsers (safari, IE and FF work differently).

On one page I'm displaying dynamic charts (JFreeChart) as images. The
charts, the data they're based on, are constantly changed by the users.
The problem (as I understand it): The web browser doesn't know that the

means incorrect data is displayed.
How can I make sure the browser always asks for a fresh image?

this.setWidth(600);
DefaultCategoryDatasetFactory retVal = new DefaultCategoryDatasetFactory();
retVal.setLegend(true);
retVal.setType(AbstractChartFactory.TYPE_BarChart);
