How it works
The Barracuda SSL VPN retrieves the Web page on behalf of the connecting client and the
information received by the appliance is processed by the replacement engine. This proxy type
attempts to find all links in the Web site code and replace them with links pointing back to the SSL
VPN server. Due to the number of ways it is possible to create links (in many different languages),
this proxy type is not always successful. However it is possible to create custom replacement values
to get a Web site working.
Authentication
Replacement and Reverse Proxy Forwards can not only access a site or an application but can also
authenticate the user accessing it. When the Web Forward connects to the URL, the additional
information provided in the Edit Web Forward page is passed in to the site, automatically
authenticating the user.
