By default, IIS in W2K3 and above will not service files that do not have the MIME type that it knows about (instead, they return 404 errors).
You need to add the MIME type to IIS so that it can serve this file type. You can install it at the site level or at the server level.
To install this for the entire server:
- Open the properties for the server in IIS Manager and click MIME Types.
- Click Create. Enter "JSON" for the extension and "application / json" for the MIME type.
Update
Given that this post is in Sencha's Getting Started Guide, I thought it was worth the steps.
Win 7 Enterprise SP 1 with 64-bit IIS has different perspectives. So the steps are:
*. Open IIS Manager. Then you will get the following window.

*. Right click MIME and select open feature
*. Click "ADD" in the upper right corner of the "Actions" menu.

*. Rest on Evan.
