Add MIME mapping in web.config for IIS Express

🌐 Adding MIME Mapping in web.config for IIS Express

So, you want to add a new MIME mapping for .woff file extensions to IIS Express using the web.config file rather than modifying the "applicationhost.config" file. But it's not working as expected, and you're getting an HTTP 404.3 error when trying to access a .woff file. Don't worry, I've got you covered! 🛡️

⚠️ The Common Issue

One common issue that might be causing this problem is the lack of the required entry in the <handlers> section of the web.config file. Adding MIME mappings for static content like .woff files alone might not be sufficient.

🎯 The Solution

To resolve this issue, you need to add the appropriate <handlers> entry in your web.config file. Here's how you can do it:

<system.webServer>
  <!-- Add this entry within the <system.webServer> section -->
  <handlers>
    <add name="FontHandler" path="*.woff" verb="GET" modules="StaticFileModule" resourceType="Either" />
  </handlers>
  ...
  <staticContent>
    <mimeMap fileExtension=".woff" mimeType="font/x-woff" />
  </staticContent>
</system.webServer>

Make sure to include the <handlers> tag and add the <add> tag within it. The name attribute can be any descriptive name you choose. The path attribute should match the file extension you want to map. In this case, it should be *.woff to match all .woff files.

💡 Explanation

The <handlers> section in the web.config file defines how IIS Express handles incoming requests for specific file types. By adding the <add> tag with the appropriate attributes, we are instructing IIS Express to treat .woff files as static files that can be served.

🚀 Test it Out

Save your web.config file with the changes and restart your application. Now, try accessing a .woff file, and you should no longer encounter the HTTP 404.3 error. Hurray! 🎉
