Adding <mimeMap> entry Causes 500 for Other Static Content on IIS Express

问题

I'm using Visual Studio 2012 with Update 2 and IIS Express.

When I add a record to the staticContent section, all other static content (.js, .css, .jpg, etc) returns a 500 error.

Any advice would be greatly appreciated. Thanks in advance.

回答1:

The mimetype is probably already added to your IIS.

Try to remove the mimetype first and then add it again in your web.config

<remove fileExtension=".woff"/>
<mimeMap fileExtension=".woff" mimeType="application/font-woff" />

Good luck!

Behavior of system.webServer/staticContent/mimeMap element has changed in IIS 7.0 and apparently one has to list all types explicitly to have them returned properly.

Here is a description from IIS configuration documentation:

Note: IIS 7 will not return file types that are not added to the element or that have mappings in the element by default. This behavior prevents unauthorized access to files that do not have mappings in the IIS 7 configuration settings.

If you are using IIS Express in visual studio then there is no need to define staticContent so remove it.

By default, Visual studio IIS Express allow all MIME types.
