IE11 HTTPS AJAX XMLHttpRequest：网络错误0x2eff，由于错误00002eff无法完成操作 [英] IE11 HTTPS AJAX XMLHttpRequest: Network Error 0x2eff, Could not complete the operation due to error 00002eff

问题描述

我有一个ajax POST请求，可能需要2秒到30多分钟。由于按钮点击而发生了帖子请求

I have an ajax POST request that can take anywhere between 2 seconds to 30+ minutes. The post request occurs as a result of button click

如果请求不到一分钟或两分钟，它会返回响应并且一切正常。但是，如果请求花费的时间超过两分钟，则会返回网络错误：XMLHttpRequest：网络错误0x2eff，由于错误00002eff无法完成操作。

If the request takes less than a minute or two, it comes back with a response and everything works fine. However if the request takes longer than two minutes it comes back with "Network error: XMLHttpRequest: Network Error 0x2eff, Could not complete the operation due to error 00002eff".

Ofcourse ，它可以很好地运行Firefox和Chrome。

Ofcourse, it works fine Firefox and Chrome.

应用程序部署在启用了SSL的JBoss服务器上。这里的架构是我们有一个负载均衡器，可以将请求路由到两个Jboss服务器。

The application is deployed on a JBoss server with SSL enabled. The architecture here is that we have a load balancer that routes the request to two Jboss servers.

我尝试了以下但是徒劳无法

1）ajax将缓存设置为false - 不起作用


2）根据 https://support.microsoft.com/en-us/kb/813827 - 没有用，这里是哪里它变得令人困惑，这表明它不是IE的东西，但同时这适用于chrome和ff所以它不是服务器的东西太多了


3）将ajax超时设置为0 - $后没有工作
4）添加了e.preventDefault（ '＃mdlSgn'）。点击（函数（）{按照 jQuery Ajax请求被取消而不被发送

1) ajax set cache to false - did not work

2) Changed registry settings as per https://support.microsoft.com/en-us/kb/813827 - did not work, here is where it gets confusing, thissuggests it is not an IE thing, but at the same time this works on chrome and ff so its not a server thing too

3) Set ajax timeout to 0 - did not work 4) Added e.preventDefault after $('#mdlSgn').click(function() { as per jQuery Ajax requests are getting cancelled without being sent

$('#mdlSgn').click(function() {
    $('#cnfdsgl').modal('hide');

     $.ajax({
        url: ajaxUrl,
        type: "POST",
        data: JSON.stringify(input),
        contentType: "application/json; charset=UTF-8",
        dataType: "json",
        success: function(data) {
             /// some logic


        },
        error : function(jqXhr, textStatus, errorThrown) {
            /// some logic
        }
    });

 //some other logic
}); 

推荐答案

可能需要2秒到30多分钟

can take anywhere between 2 seconds to 30+ minutes

我认为这是因为需要传输大量数据。

I assume this is because of large amount of data to transfer.

我创建了大型文件上传器，可处理20GB +视频文件，可能持续数小时。

I have creating large file uploader, that handles 20GB+ video files and may last for several hours.

根据我的经验 - 使用单个ajax请求上传大数据会导致奇怪的浏览器崩溃（例如我的Chrome浏览器在大约20％的上传测试中崩溃）。

In my experience - uploading large data with single ajax request can cause strange browser crashes (for example my Chrome browser crashes in about 20% of upload tests).

我发现最可靠的方法是以1MB的块分割数据，然后通过单独的ajax请求将它们顺序发送到服务器。

The most reliable way, what I found, is to split data in chunks of 1MB and send them sequentially to the server by separate ajax requests.
