瀏覽器請(qǐng)求的'/'的時(shí)候，假如服務(wù)器重定向到'/test'，這個(gè)時(shí)候請(qǐng)求'/test'的headers里面會(huì)有referer嗎？為什么？怎樣可以讓瀏覽器帶上？var express = require('express')
, http = require('http')
, path = require('path');var app = express();
app.configure(function(){
app.set('port', process.env.PORT || 8888);
app.set('views', __dirname + '/views');
app.set('view engine', 'jade');
app.use(express.favicon());
app.use(express.logger('dev'));
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(app.router);
app.use(express.static(path.join(__dirname, 'public')));
});
app.configure('development', function(){
app.use(express.errorHandler());
});
app.get('/', function(req, res, next) {
res.redirect('/test');
});
app.get('/test', function(req, res, next) {
res.send(req.headers);
});
http.createServer(app).listen(app.get('port'), function(){
console.log("Express server listening on port " + app.get('port'));
});返回：{

和瀏覽器版本有關(guān)系，標(biāo)準(zhǔn)也并沒有對(duì)此做出說明。
所以最好不要依賴referer，這也是為什么很多網(wǎng)站都會(huì)將源地址當(dāng)作參數(shù)傳過去。

正確的做法是重定向時(shí)用/?from=/test這樣的地址。瀏覽器的行為沒有辦法確定，況且還不一定是瀏覽器在發(fā)起HTTP請(qǐng)求，如果是搜索引擎spider或命令行的腳本呢？
