Security :: How To Add ApplicationName To Existing Website

I have a (internet) web site with the below web.config (everything works fine). How would I alter this to include an applicationName attribute. I wish to eventually have multiple web sites using the same ASPNETDB database.

<?xml version="1.0"?>
<configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">
<connectionStrings>
<clear/>
<add name="LocalSQLServer" connectionString="Server=myserver.com; Database=MyDB; Uid=MyUser; Pwd=MyPassword; Trusted_Connection=False;" providerName="System.Data.SqlClient"/>
</connectionStrings>
<system.web>
<customErrors mode="Off" defaultRedirect="~/Error.aspx"/>
<roleManager enabled="true"/>
<authentication mode="Forms"/>
<compilation debug="false"/>
<pages theme="Standard"/>
</system.web>
</configuration>
