问题
In my mini project i'm trying to crop an already uploaded image and then show the cropped image in place of the original image in the gallery page. But after I'm done with cropping i'm shown the the original image when i'm redirected to the gallery page even refreshing the page doesn't work. I have to clear the browser's cache in order to see the cropped image. Can i clear the browser's cache using jQuery?

Just go through this link, it is not possible to clear cache but can prevent it by using metatag "no cache" or either in http headers. but alternatively can do this by using parameters,refreashing etc. or javascript file name versioning so browser will download it always.
