Expression prefixes for VPNs and clientless VPNs

The Advanced policy engine provides prefixes that are specific to parsing VPN or Clientless VPN data. This data includes the following:

  • Host names, domains, and URLs in VPN traffic.
  • Protocols in the VPN traffic.
  • Queries in the VPN traffic.

These text elements are often URLs and components of URLs. In addition to applying the text-based operations on these elements, you can parse these elements by using operations that are specific to parsing URLs. For more information, see Expressions for extracting segments of URLs

For information about VPN expression prefixes, see VPN expression table.
