Nuget Build status

CacheBuster

A small helper for automatically cache busting static assets in .NET

How it works

The helper looks at the file's last modified date and sets the timestamp as a queryparamter on the path to the static file. This means that everytime you change the file, the browser cache will update as well.

It's inspired by this article from 2014

How to use

  1. Install the Nuget package
  2. Wrap your static assset paths in the CacheBuster method ➡️

Example

@using CacheBuster;

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8"/>
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>@ViewBag.Title - My ASP.NET Application</title>
    <link href="@CacheBuster.GetFullPath("/Content/Site.css")" rel="stylesheet">

    <script src="@CacheBuster.GetFullPath("/Scripts/modernizr-2.8.3.js")"></script>
</head>
<body>
</body>
</html>

Result

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8"/>
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Home Page - My ASP.NET Application</title>
    <link href="/Content/Site.css?v=637351943954662093" rel="stylesheet">

    <script src="/Scripts/modernizr-2.8.3.js?v=637351943957222104"></script>
</head>
<body>
</body>
</html>
