Description

Azure Web Applications define a whitelist of mime types that are allowed to be served as static content. Unfortunately, the woff format is not allowed by default. Should your site reference fonts in this format, accessing it via browser might result in a 404 status code.

Solution

Register the mime type manually in the Web.config file:

<configuration>
  <system.webServer>
    <staticContent>
      <mimeMap fileExtension="woff" mimeType="application/font-woff" />
  </staticContent>
</system.webServer>
