Answer 1

you can solve this by using UrlRewrite ,

<configuration>
    <system.webServer>
        <rewrite>
            <rules>
             <rule name="LowerCaseRule">
              <match url="[A-Z]" ignoreCase="false"/>
              <action type="Redirect" url="{ToLower:{URL}}"/>
             </rule>
            </rules>
        </rewrite>
    </system.webServer>
</configuration>
