Adding Media MIME Types to ISS

MIME type in IIS

MIME types in IIS are used to define and allow a specific file type to be served out by IIS. Usually this is used with new media files types, such as FLV, MP4, and etc.

Diagnosing the issue

If the course works fine in a locally published HTML setting and when the course is published to CourseMill the media is missing, says it’s not on the server, or it says unable to connect. This means adding a MIME type might help.

For IIS 7.0 and 7.5 1.
  1. Open IIS Manager and click on your server level settings.

  2. In Features View, double-click MIME Types.

  3. In the Actions pane, click Add.

  4. In the Add MIME Type dialog box, type a file name extension in the File name extension text box. For example, type .mp4.

  5. Type a MIME type in the MIME type text box. For example, type application/octet-stream.

  6. Click OK.

For IIS 6.0
  1. In IIS Manager, right-click the local computer, and click Properties.

  2. Click the MIME Types button.

  3. Click New.

  4. In the Extension box, type the file name extension.

  5. In the MIME type box, type a description that exactly matches the file type defined on the computer.

  6. Click OK.
