It sounds like you are using an action to render the image. What I did was
had my image rendered by page instead of the component. The component just
puts the img element into the page.
consider using expires instead or/in addition to cache-control
in your StreamResponse.
public void prepareResponse(Response response) {
Calendar c = Calendar.getInstance();
c.add(Calendar.MONTH, 1);
response.setDateHeader("Expires", c.getTimeInMillis());
}
