Description This command serves two purposes. First of all, it instructs the web browser not to cache the image, even if caching is enabled on the browser. This is useful when graphing data from a database where the data changes frequently.
Secondly, it instructs PopChart Server not to cache the image on the server side, even if caching is enabled. This latter purpose affects only PopChart Server Enterprise, as it is the only product that features server-side caching.
