Question

您好我只在亚马逊云上遇到此问题。在我的本地主机上一切都很好但是在服务器上，当请求延迟超过60秒时，它会再次以相同的时间戳重复。我有一个演示页面，它在这里提交ajax：

<div id="fb-root"></div>
<div id="results">Hello
</div>

<script>
jQuery(document).ready(function() {
jQuery.ajax({
            url : "{{ path('_sleep') }}",
            type : "GET",
            cache : false,
            dataType : 'json',
            success : function(data, textStatus, jqXHR) {
                console.log(jqXHR);
            },
            error : function(jqXHR, textStatus, errorThrown)
            {
                console.log(jqXHR);
            }
        });
})
</script>

在我的睡眠操作的服务器端，代码是：

public function sleepAction()
    {
        $logger = $this->get("logger");

        $logger->info("start sleep");
        usleep(61000000);
        $logger->info("end sleep");

        return new Response(json_encode(true));
    }

PHP访问日志如下所示：

正如您所见，请求重复3次，不包括初始请求。之后，即使我认为它会再次重复，它也会停止。我自己的日志显示：

[2013-04-22 15:52:48] logger.INFO: start sleep [] []
[2013-04-22 15:53:49] logger.INFO: end sleep [] []
[2013-04-22 15:53:49] logger.INFO: start sleep [] []
[2013-04-22 15:54:50] logger.INFO: end sleep [] []
[2013-04-22 15:54:50] logger.INFO: start sleep [] []
[2013-04-22 15:55:51] logger.INFO: end sleep [] []
[2013-04-22 15:55:51] logger.INFO: start sleep [] []
[2013-04-22 15:56:52] logger.INFO: end sleep [] []

随意提出建议。谢谢。

Ajax请求调用了两次
