Typical SharePoint page URLs can be long and hard to type or memorize. To solve this problem we have introduced a concept of friendly URLs where a long URL can be shortened to a friendlier version which is typically smaller.<6> The friendly URLs are always mapped to an underlying SharePoint page URLs.

For any transactions with the actual SharePoint object model friendly URLs cannot be used.
