Which CLI command is used to enable URL filtering support for shortened URLs on the Cisco Secure Email Gateway?

`webadvancedconfig` is not the correct command syntax for configuring shortened URL filtering on a Cisco Secure Email Gateway.

On the Cisco Secure Email Gateway (formerly ESA), the `websecurity advancedconfig` CLI command is used to access advanced configuration options for web security features, which include settings related to URL filtering and handling of shortened URLs for security analysis and rewriting.

`outbreakconfig` is used for configuring outbreak filters, which is a different email security feature, not directly related to URL filtering.

`websecurity config` is a more general command for web security, but `advancedconfig` specifically targets the settings for shortened URLs and other advanced web interaction features.
