When you use the server component, a new name is generated every time for he

image. So I don't see how it can be cached, if a different file with a

different name every time. When you do a view-source of the page that is not

"up-to-date" the HREF of the image points to the same or to a different

image ? if it points to the same, it is the page hat is being cached and you

need to configure Tomcat so that this doesn't happen (this falls out of the

scope of our products).

I'm assuming you are using Chart FX Internet 5.x (COM version). If this is

not correct, the above statement may not be true. In particular if you are

using Chart FX 6.0 and the PSS Extension caching of images can be enabled.
