<system.webServer>
<modules>
<remove name="FormsAuthentication" />
</modules>
<handlers>
<add name="MiniProfiler" path="mini-profiler-resources/*" verb="*" type="System.Web.Routing.UrlRoutingModule" resourceType="Unspecified" preCondition="integratedMode" />
</handlers>
<staticContent>
<remove fileExtension=".woff" />
<remove fileExtension=".woff2" />
<mimeMap fileExtension=".woff" mimeType="application/x-woff" />
<mimeMap fileExtension=".woff2" mimeType="application/x-woff2" />
</staticContent>
</system.webServer>
