This can cause a problem when trying to reload an image that > changes often (which can be a problem during testing). To work around > this, add ?chid=value at the end of the POST URL, where value changes > with every request: the chart server will ignore this parameter, and > the browser will resend the query, and not simply reload the cached > version." > > This was a tip given so that the page will refresh.
