Chapter 38 Clientless SSL VPN
Configuring Application Helper
Configuring Application Helper
Clientless SSL VPN includes an Application Profile Customization Framework option that lets the
security appliance handle non-standard applications and web resources so they display correctly over a
Clientless SSL VPN connection. An APCF profile contains a script that specifies when (pre, post), where
(header, body, request, response), and what data to transform for a particular application. The script is
in XML and uses sed (stream editor) syntax to transform strings/text.
Typically, Cisco TAC helps you write and apply an APCF.
You can configure multiple APCF profiles on a security appliance to run in parallel. Within an APCF
profile script, multiple APCF rules can apply. In this case, the security appliance processes the oldest
rule first, based on configuration history, the next oldest rule next, and so forth.
You can store APCF profiles on the security appliance flash memory, or on an HTTP, HTTPS, FTP, or
TFTP server. Use this panel to add, edit, and delete APCF packages, and to put them in priority order.
Fields
• APCF File Location—Displays information about the location of the APCF package. This can be on
the security appliance flash memory, or on an HTTP, HTTPS, FTP, or TFTP server.
• Add/Edit—Click to add or edit a new or existing APCF profile.
• Delete—Click to remove an existing APCF profile. There is no confirmation or undo.
• Move Up—Click to rearrange APCF profiles within a list. The list determines the order in which the
security appliance attempts to use APCF profiles.
Add/Edit APCF Profile
This panel lets you add or edit and APCF package, which includes identifying its location, which can be
either on the security appliance flash memory, or on an HTTP, HTTPS, or TFTP server.
