No Mime Types Option in IIS 7

iis-7.5mime-types

I have a problem in IIS whereby I have installed a web applcation that runs using .NET but when you navigate to it none of the images are displayed and the CSS is not being used, so the page is completely unformatted.

I am stumped by this but I was wondering if it could be something to do with permitted MIME types, so was going to check which ones were permitted when i noticed tghat the MIME types option is not present.

I can see it in IIS on another server in the IIS section when you click on a site, but it is just not present on this server. Does anyone know:

a) Why it is not there and how you can get it back
b) If it could be the cause of the problem whereby the CSS is not detected and no images are shown?

I hope that I've explained this properly but will be happy to provide any more information to anyone that is happy to help!! 🙂

Thanks

To solve the missing (blank CSS) and image issue, you need to install the Static Content Role.

Start -> Administrative Tools -> Server Manager
Select Web Server under Roles
Third option down is Static Content under Common Http Features
Install it

Your static content will now be served.

If you need to add specific MIME types then you can use the newly installed MIME Types feature. The new Role will not be shown until you restart IIS Manager.

The 2^nd option is the one you want.

In your web.config, make sure these keys exist:

<configuration>
    <system.webServer>
        <validation validateIntegratedModeConfiguration="false"/>
    </system.webServer>
</configuration>
