IIS 7 Mime type modification without iis 7 manager | fix svg wrong mime type | svg not appearing

I'm quite ignorant about IIS 7 but after using ii7 manager I've noticed that it's easier than expected to modify
the preconfigured mime types and *any* (I don't know exactly what can be modified or not) other configuration
by adding/modifying "web.config" in the root directory.

This sample file web.config is a modification for the svg that have a wrong mime type and the svg are not showing correctly.



web.config
--------------------------------------------------------------------------

<configuration>
    <system .webserver="">
        <staticcontent>
            <remove fileextension=".svg2">
            <remove fileextension=".svg">
            <mimemap fileextension=".svg" mimetype="image/svg+xml">
            <mimemap fileextension=".svg2" mimetype="image/svg+xml">
        </mimemap></mimemap></remove></remove></staticcontent>
    </system>
</configuration>
--------------------------------------------------------------------------

With this modification in web.config (and there's no need to use any manager)
we can reconfigure the mime type to "image/svg+xml".
On an aruba, ngi servers I've got "image/svg xml" .... that seems to be wrong and gives problems on most of the browsers.

More things can be modified/added.
