How to configure Spring to call an image serving servlet from the dispatcher servlet?

Question

I've written the code for a servlet to serve images in my app from a url such as:

/imgsrv?imgid=12345

So this would be one additional servlet in the app besides the Dispatcher servlet.

The problem is, I don't know how do you configure Spring to call this new servlet from the Dispatcher servlet?

Answer 1

Can you make it clear that why you should call the new servlet from the Dispatcher servlet, what not just add a new servlet?
