deployments, you might be concerned about network vulnerabilities between the
NetScaler appliance and the backend servers, or you might need complete
end-to-end security and interaction with certain devices that can communicate
only in clear text (for example, caching devices).
In such cases, you
can set up an HTTP virtual server that receives data from clients that connect
to it at the front end and hands the data off to a secure service, which
securely transfers the data to the web server.
To implement this
type of configuration, you configure an HTTP virtual server on the NetScaler
and bind SSL based services to the virtual server. The NetScaler receives HTTP
requests from the client on the configured HTTP virtual server, encrypts the
data, and sends the encrypted data to the web servers in a secure SSL session.
To configure SSL
acceleration with HTTP on the front-end and SSL on the back-end, first enable
the load balancing and SSL features on the NetScaler. Then, add SSL based
services that represent secure servers to which the NetScaler appliance will
send encrypted data. Finally, add an HTTP based virtual server and bind the SSL
services to this virtual server.
