I’m trying to implement a web-app using gwt. I’m using alot of images (read 1000+, about 200mb), in a low-res . I would like the user to be able to choose to either cache the images forever (if its possible), download them as needed, or the user himself has them in his/her PC and points the app to their location, and it uses them instead. So the question is, is it possible using gwt to save a huge cache indefinetly? Or have the user use it’s own images instead.
You can configure your web server to set the expires headers on the images to a date very far in the future, that will tell the browser to effectively cache the images for ‘forever’. This is not really something I would try to do in GWT when the browser can do it for you.
