When faced with this problem I wrote a series of wrapper functions around the <code>UrlHelper</code>'s <code>Content</code> method:

EDIT:

Following the discussions in the comments below I updated this code:

<pre><code>public static class UrlHelperExtensions
{
 private readonly static string _version = System.Reflection.Assembly.GetExecutingAssembly().GetName().Version.ToString();

 private static string GetAssetsRoot()
 {
 string root = ConfigurationManager.AppSettings["AssetsRoot"];
 return root.IsNullOrEmpty() ? "~" : root;
 }

 public static string Image(this UrlHelper helper, string fileName)
 {
 return helper.Content(string.Format("{0}/v{2}/assets/img/{1}", GetAssetsRoot(), fileName, _version));
 }

 public static string Asset(this UrlHelper helper, string fileName)
 {
 return helper.Content(string.Format("{0}/v{2}/assets/{1}", GetAssetsRoot(), fileName, _version));
 }

 public static string Stylesheet(this UrlHelper helper, string fileName)
 {
 return helper.Content(string.Format("{0}/v{2}/assets/css/{1}", GetAssetsRoot(), fileName, _version));
 }

 public static string Script(this UrlHelper helper, string fileName)
 {
 return helper.Content(string.Format("{0}/v{2}/assets/js/{1}", GetAssetsRoot(), fileName, _version));
 }
}
</code></pre>

Using these functions in conjunction with the following <code>rewrite</code> rule should work:

<pre><code>&lt;rewrite&gt;
 &lt;rules&gt;
 &lt;rule name="Rewrite assets"&gt;
 &lt;match url="^v(.*?)/assets/(.*?)" /&gt;
 &lt;action type="Rewrite" url="/assets/{R:2}" /&gt;
 &lt;/rule&gt;
 &lt;/rules&gt;
&lt;/rewrite&gt;
</code></pre>

<a href="http://learn.iis.net/page.aspx/461/creating-rewrite-rules-for-the-url-rewrite-module/">This article</a> discusses how to create rewrite rules on IIS7.

This code uses the version number of the current assembly as a query string parameter on the file path's it emits. When I do an update to the site and the build number increments, so does the querystring parameter on the file, and so the user agent will re-download the file.

blocks|key|1020777|text|我认为下一个具有高级选项(调试/发布模式、版本)的解决方案：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1020778|通过以下方式包含的Js或Css文件：|1020779|<script+type="text/javascript"+src="Scripts/exampleScript<%25=Global.JsPostfix%25>"+/>

I suppose next solution with advanced options (debug/release mode, versions):

Js or Css files included by such way:

<pre><code>&lt;script type="text/javascript" src="Scripts/exampleScript&lt;%=Global.JsPostfix%&gt;" /&gt;
&lt;link rel="stylesheet" type="text/css" href="Css/exampleCss&lt;%=Global.CssPostfix%&gt;" /&gt;
</code></pre>

Global.JsPostfix and Global.CssPostfix is calculated by the following way in Global.asax:

<pre><code>protected void Application_Start(object sender, EventArgs e)
{
 ...
 string jsVersion = ConfigurationManager.AppSettings["JsVersion"];
 bool updateEveryAppStart = Convert.ToBoolean(ConfigurationManager.AppSettings["UpdateJsEveryAppStart"]);
 int buildNumber = System.Reflection.Assembly.GetExecutingAssembly().GetName().Version.Revision;
 JsPostfix = "";
#if !DEBUG
 JsPostfix += ".min";
#endif 
 JsPostfix += ".js?" + jsVersion + "_" + buildNumber;
 if (updateEveryAppStart)
 {
 Random rand = new Random();
 JsPosfix += "_" + rand.Next();
 }
 ...
}
</code></pre>

I have read lots of article on how to auto-version your CSS/JS files - but none of these really provide an elegant way to do this in ASP.NET MVC.

This link - <a href="https://stackoverflow.com/questions/118884/what-is-an-elegant-way-to-force-browsers-to-reload-cached-css-js-files">How to force browser to reload cached CSS/JS files?</a> - provides a solution for Apache - but I'm a little confused how this could be implemented via ASP.NET MVC ?

Would anyone be able to provide some advice how to do this on IIS7 and ASP.NET MVC - so that CSS/JS files automatically have a version number inserted in the URL without changing the location of the file ?

That is, so links come out link this etc presumably using the URL Rewrite or ?

<pre><code>&lt;link rel="stylesheet" href="/css/structure.1194900443.css" type="text/css" /&gt;
&lt;script type="text/javascript" src="/scripts/prototype.1197993206.js"&gt;&lt;/script&gt;
</code></pre>

Thx
