Hello Jacob
we have setting the response header like this
app.all('*', function(req, res, next) {
res.header("Access-Control-Allow-Origin", "*");
res.header("Access-Control-Allow-Headers", "X-Requested-With");
res.header("Access-Control-Allow-Methods","PUT,POST,GET,DELETE,OPTIONS");
res.header("X-Powered-By",' 3.2.1')
res.header("Content-Type", "application/json;charset=utf-8");
if(req.method==='OPTIONS')
res.send(200);
else
next();
});
so is there anything we have to setting on node.js server?
and how could i check the second request can be received successfully?
or did you have any ie ajax success sample can show me? because it is
really strange
thanks a lot Jacob~
