我注意到Safari 5.0.5(6533.21.1)似乎正在提交重复的ajax调用.当我运行以下简化测试用例时:

// jquery 1.6 include
$(document).ready(function() {
    setTimeout(function(e) {
        var req1 = $.getJSON('/api/private/customers.json');
        console.log('req1 sent');
    }, 2000);
    setTimeout(function(e) {
        var req2 = $.getJSON('/api/private/customers.json');
        console.log('req1 sent');
    }, 4000);
});

Safari资源面板和控制台显示两个xhr请求,但我的服务器日志显示三个xhr请求:
