I ran into this problem too. It looks like there is some caching
going on so that repeated requests with the same list of stocks will
return cached results. I was able to fix this by adding the following
code to the top of the doGet method in JsonStockData:
if (req.getProtocol().compareTo("HTTP/1.0") == 0) {
resp.setHeader("Pragma", "no-cache");
} else if (req.getProtocol().compareTo("HTTP/1.1") == 0) {
resp.setHeader("Cache-Control", "no-cache");
}
resp.setDateHeader("Expires", 0);
