Define Mime Types on Cloud Sites (Windows)

MIME types control the way a server attempts to complete requests from a web server. To load a file on your website, a MIME type extension must be defined. You can add a custom MIME type extension by adding code to your web.config file.

To add an additional extension or change the MIME type for an extension, use the following code:

<configuration>
<system.webServer>
        <staticContent>
            <remove fileExtension=".extension" />
            <mimeMap fileExtension=".extension" mimeType="application/example" />
        </staticContent>
    </system.webServer>
</configuration>

For example, you might want to change the server level .pdf mime type of .pdf application/pdf to application/octet-stream. You must include a remove fileExtension tag to avoid getting a 500 error.

We recommend that you add a remove fileExtension tag even if the extension is not in our list. That way, if we ever add it to the server level, it will not cause a 500 error because of a duplicate MIME type extension.

The following example shows the described change:

<configuration>
<system.webServer>
        <staticContent>
            <remove fileExtension=".pdf" />
            <mimeMap fileExtension=".pdf" mimeType="application/octet-stream" />
        </staticContent>
    </system.webServer>
</configuration>
