Hey there,
Sitecore 6 provides a functionality to embed your language as parts in the url e.g. http://www.test.com/en-US/test.aspx.
You can control this feature by using the web.config entries:
<linkManager defaultProvider=”sitecore”>
<providers>
<clear/>
<add name=”sitecore” type=”Sitecore.Links.LinkProvider, Sitecore.Kernel” addAspxExtension=”true” alwaysIncludeServerUrl=”false” encodeNames=”true” languageEmbedding=”asNeeded” languageLocation=”filePath” shortenUrls=”true” useDisplayName=”false”/>
</providers>
</linkManager>
Cheers chris
