本文介绍了XmlHttpRequest在IE中比在Chrome中需要更多时间吗？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！问题描述

我使用的是一个Web应用程序（这真的很大），所以应用程序的某些部分我真的不知道它们是如何工作的。

我是一名前端开发人员，我正在使用.NET Web Api实现一个REST API（据我所知）

请求很简单 - 我使用kendo数据源从这个服务器获取数据像这样

以下是我从另一个请求中检查第一个IE请求中的时间分配的额外信息

正如您所看到的，最大的部分是请求，这是发送请求并接收服务器的第一个响应所需的时间。

解决方案

这个问题可能是Windows身份验证打开的文件夹，你正在调用ajax ... 同样的原则适用于这里...

docs.telerik/ kendo-ui / web / upload / troubleshooting

问题：在Windows身份验证中使用IE10 / 11时，异步上传会随机失败如果HTTP POST上收到401质询，则上传会无限期冻结或超时。

解决方案

对于IE10，请参阅 KB2980019

截至2014年11月6日，没有针对IE 11的官方修复程序。请参阅bug ID 819941

I'm using a Web App (which is really big) so there are some parts of the application that I really don't know how they work.

I am a front end developer and I'm consuming a REST API implemented with .NET Web Api (as far as I know)

The request is simple - I use kendo Datasource to get the data from the server like this

and the request for the data

$http({ method: 'GET', url: 'REST/SystemDataSet/' + id + '/Values' }).success(function (response) { // store data lookupValues = response; kendoDataSource.read(); // do some logic here }).error(function(error) { // logic });

I do this in this way because there is some extra logic that manipulates the data.

This request in Chrome takes like 32 ms while it takes almost 9 seconds in IE. The data retrieved is the same (you can see the Size of response), which is an array of JSon objects (Very simple)

I don't know exactly if there is a cache mechanism in the backend, but it shouldn't matter because I'm able to reproduce it like this every time (fast in Chrome, really really slow on IE)

Any ideas of what could be causing this behaviour ? As I understand, if there is a cache or something, it should be the same for every browser, so this should be happening on both and not only on IE - the backend is agnostic of the browser.

Here is some extra information I have from another request to check the distribution of time in the first IE request

As you can see, the biggest part is the "Request", which is the Time taken to send the request and receive the first response from the server.

Thanks in Advance

The problem is probably Windows Authentication turned on for the folder you are calling the ajax from... Same principle applies here ...

docs.telerik/kendo-ui/web/upload/troubleshooting

Problem: Async uploads randomly fail when using IE10/11 with Windows Authentication The upload either freezes indefinitely or times out if a 401 challenge is received on the HTTP POST.
