Image not being retrieved from browser cache - gwt upload

I am using gwt-upload to upload an image to my server. In the response back to the client, I am getting the file url in this format.

http://myServer.com/myApplication/servlet.gupld?show=GWTU-036386735388077796

Now, I try to make a copy of this image on my client to enable cropping by the user. However, when I create an img tag with this same url, the image is being retrieved from the server and not from the cache. Can somebody please provide a solution for this problem?

Looks like you are using custom servlet to return images. Do you set correct HTTP headers to the response, so the browser knows that images can be cached?

Here is a tutorial how to implement it using servlets
