Optimizing JS and CSS files by merging and compressing in ASP.NET MVC

I started with a default ASP.NET MVC 3 web application and decided to enhance it by adding three CSS and three JS files to the \Views\Shared_Layout.cshtml view:

<!DOCTYPE html>
<html>
<head>
    <title>@ViewBag.Title</title>
    <link href="@Url.Content("~/Content/Site.css")" rel="stylesheet" type="text/css" />
    <link href="@Url.Content("~/Content/StyleSheet1.css")" rel="stylesheet" type="text/css" />
    <link href="@Url.Content("~/Content/StyleSheet2.css")" rel="stylesheet" type="text/css" />

    <script src="@Url.Content("~/Scripts/jquery-1.5.1.min.js")" type="text/javascript"></script>
    <script src="@Url.Content("~/Scripts/JScript1.js")" type="text/javascript"></script>
    <script src="@Url.Content("~/Scripts/JScript2.js")" type="text/javascript"></script>

</head>
<body>
    <div class="page">
        <div id="header">

....

Upon running the application, the HTML code generated looks like this:

<!DOCTYPE html>
<html>
<head>
    <title>Home Page</title>
    <link href="/Content/Site.css" rel="stylesheet" type="text/css" />
    <link href="/Content/StyleSheet1.css" rel="stylesheet" type="text/css" />
    <link href="/Content/StyleSheet2.css" rel="stylesheet" type="text/css" />

    <script src="/Scripts/jquery-1.5.1.min.js" type="text/javascript"></script>
    <script src="/Scripts/JScript1.js" type="text/javascript"></script>
    <script src="/Scripts/JScript2.js" type="text/javascript"></script>

</head>
<body>
    <div class="page">

Now, I am looking for a way in MVC to have a handler that changes the output HTML to look like this:

<!DOCTYPE html>
    <html>
    <head>
        <title>Home Page</title>
        <script src="js.axd=/Scripts/jquery-1.5.1.min.js,/Scripts/JScript1.js,/Scripts/JScript2.js" type="text/javascript"></script>
        <link href="css.axd=/Content/Site.css,/Content/StyleSheet1.css,/Content/StyleSheet2.css" rel="stylesheet" type="text/css" />
    </head>
    <body>
        <div class="page">

This means that 

js.axd=/Scripts/jquery-1.5.1.min.js,/Scripts/JScript1.js,/Scripts/JScript2.js
will return the content of all these JS files to the browser, while 
css.axd=/Content/Site.css,/Content/StyleSheet1.css,/Content/StyleSheet2.css
will return the content of all CSS files.

I have used IHttpHandler before in ASP.NET, but struggling to implement it in MVC as I am still new to it.

Any assistance or sample code would be greatly appreciated. Thank you!
