How do I define a MIME Type in cPanel?

Introduction

You may run into a scenario that requires defining a custom Mime Type for various content for your sites to operate normally (for example, running WebAssembly code that requires a Content-Type to be defined).

Below is how you define this information in cPanel.

Procedure

From https://docs.cpanel.net/cpanel/advanced/mime-types/

To add a MIME type, perform the following steps:

1. Enter the name of the file type’s handler in the MIME Type text box.
   • For example, application/cgi represents the handler for .cgi file extension.
2. Enter the file extension in the Extension(s) text box.
   • A file extension represents the letters after the dot (.) in a file name. For example, filename.fileextension.
3. Click Add.
