You can define more than one source URL for any URL iView. Apart from the default URL, which is not language-specific, you can define any number of additional URLs; each one corresponding to a different language.
If a portal user’s language matches a language defined in the iView, then the corresponding language-specific URL will be executed at runtime. The default URL functions as the fallback URL if no language-specific URL matches the user’s language.
Defining multiple URLs per iView is useful for sites that support multiple languages by means of language-specific URLs; for example, you can define URLs that are language variants of the default www.google.com URL of Google, such as www.google.de and www.google.jp. In other cases, you can define in the same iView, variant URLs which reference different Web sites.
