blocks|key|576837|text|这可能不能回答您的问题，但是我在新的IIS安装中遇到了同样的症状。CSS、JS和图像没有出现。是由于IIS+7.5中未安装“静态内容”角色造成的。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|576838|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

This might not answer your question but I've been banging my head with the same symptoms with a new IIS installation. CSS, JS and images were not showing up. Was due to the "Static Content" role not being installed in IIS 7.5.

blocks|key|577170|text|一个可能的原因是您的应用程序期望在端口443+(标准SSL端口)上运行，而端口443已经在使用中。当Skype在他们的计算机上运行时，开发人员试图运行我们的应用程序，我遇到过几次这样的情况。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|577171|令人难以置信的是，Skype在端口443上运行。在我看来，这是一个可怕的设计缺陷。如果你看到你的应用程序试图在444而不是443上运行，关闭Skype，这个问题就会消失。|577172|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

One possible cause of this is that your application expects to run on port 443 (standard SSL port) and port 443 is already in use. I have run into this several times with developers trying to run our application while Skype is running on their computers.

Incredibly, Skype runs on port 443. This is a horrible design flaw in my opinion. If you see your application trying to run on 444 instead of 443, shut down Skype and the problem will go away.

blocks|key|361462|text|我过去发现的一个建议对在本地主机测试环境中使用生产站点的副本开发站点很有帮助。确保注释掉规范标记：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|361463|++|code-block|syntax|javascript|361464|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

One suggestion I have found helpful in the past when developing sites in localhost test environment when working with a copy of production site. Make sure that you comment out the canonical tags:

<pre><code> &lt;!--&lt;base href="http://www.example.com/"&gt;//--&gt;

blocks|key|577274|text|如果您尝试了上述所有解决方案，但仍然存在问题，请考虑使用ASP.NET的ResolveClientUrl()方法。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|577275|脚本，例如：|577276|不是使用|577277|<script+src="~/dist/js/app.min.js"+></script>|code-block|syntax|javascript|577278|使用方法|577279|<script+src="<%25=+ResolveClientUrl("~/dist/js/app.min.js")+%25>"+></script>|577280|这是我的解决方案，对一个我正在帮助的朋友很有效！|577281|entityMap^0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|S|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|T|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|U|8|@]|9|@]|A|$]]|$1|F|3|G|5|H|7|V|8|@]|9|@]|A|$I|J]]|$1|K|3|L|5|6|7|W|8|@]|9|@]|A|$]]|$1|M|3|N|5|H|7|X|8|@]|9|@]|A|$I|J]]|$1|O|3|P|5|6|7|Y|8|@]|9|@]|A|$]]|$1|Q|3|-4|5|6|7|Z|8|@]|9|@]|A|$]]]|R|$]]

If you tried all the above solutions and still have problems, consider using the method ResolveClientUrl() of ASP.NET .

A script for Example :

Instead of using

<pre><code>&lt;script src="~/dist/js/app.min.js" &gt;&lt;/script&gt;
</code></pre>

Use the method

<pre><code>&lt;script src="&lt;%= ResolveClientUrl("~/dist/js/app.min.js") %&gt;" &gt;&lt;/script&gt;
</code></pre>

This was my solution that worked for a friend I was helping!

blocks|key|361574|text|我的痛苦是由于在web.config中定义MIME类型。我需要在开发服务器上使用它，但是本地IIS讨厌它，因为它复制了MIME类型...一旦我从web.config中删除了这些，js、css和图像不能加载的问题就消失了。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|361575|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

My hour of pain was due to defining MIME types in the web.config. I needed this for the development server but local IIS hated it because it duplicated MIME types... once I removed these from the web.config the problem with js, css, and images not loading went away.

blocks|key|361761|text|我也有同样的问题。对我来说，这是因为在IIS中，服务器级别的Cache-Control头被设置为no-cache，no-store。因此，对于我的应用程序，我必须在我的web.config中添加以下内容：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|361762|<httpProtocol>

I had this same problem. For me, it was due to Cache-Control header being set at the server level in IIS to no-cache, no-store. So for my application I had to add in the below to my web.config:

<pre><code>&lt;httpProtocol&gt;
 &lt;customHeaders&gt;
 &lt;remove name="Cache-Control" /&gt;
 &lt;/customHeaders&gt;
&lt;/httpProtocol&gt;

This is an authentication issue. In my case, it solved by below steps:
1- Go to IIS manager, in the left pane, expand the server root and select your web application from Sites node.
2- In the Home screen, go to IIS section and select Authentication.
3- Enable Anonymous Authentication.
4- Then, select Edit and set Edit Anonymous Authentication Credentials to Application pool identity.

This issue occurs when IIS does not render the static contents like your JS, CSS, Image files. 

To resolve this issue, you need to follow the below steps:

GO to Control Panel > Turn Windows features on or off > Internet Information Services > World Wide Web Services > Common HTTP Features > Static Content.

Ensure that static content is turned on. 

Bingo. And you are done. Hard-reload the page and you will be able to see all the static contents.

I had exact same problem, tried all of the suggestions but got nothing. Bugged me hours. Turned out my ISP blocked port 80 for some reasons. 

Advice: check your traffic. Make sure port 80 works both locally (i.e. firewall) and externally.

My all applications were working fine but suddenly all sites under IIS are not loading css, images, scripts. It redirect to login page. 

If i login it works fine. e.g. mysite.com/Account/LogOn?ReturnUrl=%2fpublic%2fimages%2ficons%2f41.png

On my local machine it works fine without login.
