ASP.NET

I am applying different globalization settings for main and sub directory.

<location path="." inheritinchildapplications="false">
<system.web>
 <globalization resourceproviderfactorytype="something" uiculture="auto" enableclientbasedculture="true" />
</system.web>
</location>

and

<location path="Forum">
    <system.web>
      <globalization uiculture="ar-SA" />
    </system.web>
  </location>

But only one setting works at a time. Please suggest.
