Managing client connections properly helps to ensure that your applications remain available to users even when your Citrix ADC appliance is experiencing high loads. Various load balancing features and other features available on the appliance can be integrated into a load balancing setup to process load more efficiently, divert it when necessary, and prioritize the tasks that the appliance must perform:

Sessionless load balancing. You can configure sessionless load balancing virtual servers and perform load balancing without creating sessions in configurations that use DSR or intrusion detection systems (IDS).
Integrated caching. You can redirect HTTP requests to a cache.
Priority queuing. You can direct requests based on priority, by integrating your configuration with the Priority Queuing feature.
SureConnect. You can use load balancing with the Sure Connect feature to redirect important requests to a custom webpage, insulating them from delays due to network congestion.
Delayed cleanup. You can configure delayed cleanup of virtual server connections to prevent the cleanup process from using CPU cycles during periods when the Citrix ADC appliance is experiencing high loads.
Rewrite. You can use the Rewrite feature to modify port and protocol when performing HTTP redirection, or insert the virtual server IP address and port into a custom Request header.
RTSP NAT.
Rate-based monitoring. You can enable rate-based monitoring to divert excess traffic.
Layer 2 Parameters. You can configure a virtual server to use the L2 parameters to identify a connection.
ICMP Response. You can configure the appliance to send ICMP responses to PING requests according to your settings. On the IP address corresponding to the virtual server, set the ICMP RESPONSE to VSVR_CNTRLD, and on the virtual server, set the ICMP VSERVER RESPONSE. The following settings can be made on a virtual server:
- When you set ICMP VSERVER RESPONSE to PASSIVE on all virtual servers, the appliance always responds.
- When you set ICMP VSERVER RESPONSE to ACTIVE on all virtual servers, the appliance responds even if one virtual server is UP.
- When you set ICMP VSERVER RESPONSE to ACTIVE on some and PASSIVE on others, the appliance responds even if one virtual server set to ACTIVE is UP.
