I'm developing a portlet that should show an image that should be refreshed every X seconds (only the image, not the browser because of other portlets).
If I try to open the same image URL with Cewolf I get the same image, even if the data changed because the logic on the servlet doesn't get to the data producer.
I'd like to know if there is any way I can change this behavior (some option, configuration, parameter somewhere...), so I can always get an image with the updated values, or I will have to create new code to get that functionality.
For the refresh, I intend using an adaptation of the code found in http://www.htmlcodetutorial.com/help/archive.php/o_t__t_253__refresh-one-image-only.html
The problem is that the img url points to a prerendered image on the server. Thus, same img id returns the same image.
What you could do is to write a JSP that just returns the <img> tag and use AJAX technologies to incorporate this tag into your page dynamically. Cewolf needs a full JSP server roundtrip to render a new image.
