Use Case 3: Configuring SSL Acceleration with HTTP on the Front End and SSL on the Back End

May 26, 2015

In certain 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.


Enable load balancing and SSL acceleration on the NetScaler.

After enabling load balancing and SSL acceleration, create two SSL based services, Service-SSL-1 and Service-SSL-2, with IP addresses and, and both using port 443.

Then create an HTTP based virtual server, Vserver-HTTP-1, with an IP address of

Bind the SSL services to the virtual server to complete the configuration.
