Chapter 5 Configuring Virtual Servers

Configuring Virtual Servers

the ACE appliance enables enterprises to optimize network performance and improve access to critical

business information. This capability accelerates the performance of Web applications, including

customer relationship management (CRM), portals, and online collaboration by up to 10 times.

See the “Configuring Application Acceleration and Optimization” section on page 13-1 or the

Application Acceleration and Optimization Guide, Cisco ACE 4700 Series Application Control Engine

Appliance for more information about application acceleration and optimization.

Use this procedure to configure acceleration and optimization on virtual servers.

Assumption

A virtual server has been configured. See the “Configuring Virtual Servers” section on page 5-2 for

information on configuring a virtual server.

Consideration

Application acceleration and optimization is only supported in IPv4 to IPv4 server load-balancing

configurations.

Procedure

Step 1 Select Config > Virtual Contexts > context > Load Balancing > Virtual Servers. The Virtual Servers

table appears.

Step 2 Select the virtual server you want to configure for optimization, and then click Edit. The Virtual Server

configuration screen appears.

Step 3 Click Application Acceleration And Optimization. The Application Acceleration And Optimization

configuration pane appears.

Step 4 In the Configuration field, indicate the method you want to use to configure application acceleration and

optimization:

• EZ—Indicates that you want to use standard acceleration and optimization options. Continue with

Step 5.

• Custom—Indicates that you want to associate specific match criteria, actions, and parameter maps

for application acceleration and optimization for this virtual server. If you choose this option,

continue with Step 6.

Step 5 If you select EZ, the Latency Optimization (FlashForward) and Bandwidth Optimization (Delta) fields

appear.

a. Check the Latency Optimization (FlashForward) check box to indicate that the ACE appliance is to

use bandwidth reduction and download acceleration techniques to objects embedded within HTML

pages. Clear this check box to indicate that the ACE appliance is not to employ these techniques to

objects embedded within HTML pages. Latency optimization corresponds to FlashForward

functionality. For more information about FlashForward functionality, see the “Optimization

Overview” section on page 13-2.

b. Check the Bandwidth Optimization (Delta) check box to indicate that the ACE appliance is to

dynamically update client browser caches with content differences, or deltas. Clear this check box

to indicate that the ACE appliance is not to dynamically update client browser caches. Bandwidth

optimization corresponds to action list Delta optimization. For more information about Delta

optimization, see the “Optimization Overview” section on page 13-2 and the “Configuring an HTTP

Optimization Action List” section on page 13-3.

c. Continue with Step 11.
