Managing client connections
To ensure efficient management of client connections, you can configure the content switching virtual servers on the Citrix ADC appliance to use the following features:
- Configuring the ICMP Response.You can configure the Citrix ADC 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 virtual server RESPONSE. The following settings can be made on a virtual server:
- When you set ICMP virtual server RESPONSE to PASSIVE on all virtual servers, the Citrix ADC appliance always responds.
- When you set ICMP virtual server RESPONSE to ACTIVE on all virtual servers, the ADC appliance responds even if one virtual server is UP.
- When you set ICMP virtual server RESPONSE to ACTIVE on some and PASSIVE on others, the ADC appliance responds even if one virtual server set to ACTIVE is UP.
Redirecting Client Requests to a Cache
Citrix ADC缓存重定向功能重定向HTTP requests to a cache. You can significantly reduce the burden of responding to HTTP requests and improve your website performance through proper implementation of the cache redirection feature.
A cache stores frequently requested HTTP content. When you configure cache redirection on a virtual server, the Citrix ADC appliance sends cacheable HTTP requests to the cache and non-cacheable HTTP requests to the origin Web server. For more information on cache redirection, see “Cache Redirection.
To configure cache redirection on a virtual server by using the CLI
At the command prompt, type:
set cs vserver \
Example
set cs vserver Vserver-CS-1 -cacheable yes
To configure cache redirection on a virtual server by using the GUI
- Navigate toTraffic Management > Content Switching > Virtual Servers, and open a virtual server.
- InAdvanced Settings, selectTraffic Settings, and selectCacheable.
Enabling Delayed Cleanup of Virtual Server Connections
Under certain conditions, you can configure the down state flush setting to terminate existing connections when a service or a virtual server is marked DOWN. Terminating existing connections frees resources and in certain cases speeds recovery of overloaded load balancing setups.
To configure the down state flush setting on a virtual server by using the CLI
At the command prompt, type:
set cs vserver \
Example
set cs vserver Vserver-CS-1 -downStateFlush enabled
To configure the down state flush setting on a virtual server by using the GUI
- Navigate toTraffic Management > Content Switching > Virtual Servers, and open a virtual server.
- InAdvanced Settings, selectTraffic Settings, and then selectDown State Flush.
Rewriting Ports and Protocols for Redirection
Virtual servers and the services that are bound to them might use different ports. When a service responds to an HTTP connection with a redirect, you might need to configure the Citrix ADC appliance to modify the port and the protocol to ensure that the redirection goes through successfully. You do it by enabling and configuring the redirectPortRewrite setting.
一个虚拟服务器上配置HTTP重定向by using the CLI
At the command prompt, type:
设置cs vserver \ <名称\ > -redirectPortRewrite \ <瓦尔ue\>
Example
set cs vserver Vserver-CS-1 -redirectPortRewrite enabled
一个虚拟服务器上配置HTTP重定向by using the GUI
- Navigate toTraffic Management > Content Switching > Virtual Servers, and open a virtual server.
- InAdvanced Settings, selectTraffic Settings, and selectRewrite.
Inserting the IP Address and Port of a Virtual Server in the Request Header
If you have multiple virtual servers that communicate with different applications on the same service, you must configure the Citrix ADC appliance to add the IP address and port number of the appropriate virtual server to the HTTP requests that are sent to that service. This setting allows applications running on the service to identify the virtual server that sent the request.
If the primary virtual server is down and the backup virtual server is up, the configuration settings of the backup virtual server are added to the client requests. If you want the same header tag to be added, regardless of whether the requests are from the primary virtual server or backup virtual server, you must configure the required header tag on both virtual servers.
Note
This option is not supported for wildcard virtual servers or dummy virtual servers.
To insert the IP address and port of the virtual server in the client requests by using the CLI
At the command prompt, type:
set cs vserver \
Example
set cs vserver Vserver-CS-1 -insertVserverIPPort 10.201.25.136:80
To insert the IP address and port of the virtual server in the client requests by using the GUI
- Navigate toTraffic Management > Content Switching > Virtual Servers, and open a virtual server.
- InAdvanced Settings, selectTraffic Settingsand, in the Virtual Server IP Port Insertion list, select VIPADDR or V6TOV4MAPPING, and specify a port header in the virtual server IP Port Insertion Value.
Setting a Time-out Value for Idle Client Connections
You can configure a virtual server to terminate any idle client connections after a configured time-out period elapses. When you configure this setting, the Citrix ADC appliance waits for the time you specify and, if the client is idle after that time, it closes the client connection.
To set a time-out value for idle client connections by using the CLI
At the command prompt, type:
set cs vserver \
Example
set cs vserver Vserver-CS-1 -cltTimeout 100
To set a time-out value for idle client connections by using the GUI
- Navigate toTraffic Management > Content Switching > Virtual Servers, and open a virtual server.
- InAdvanced Settings, selectTraffic Settings, and specify aClient Idle Time-Outvalue.
Identifying Connections with the 4-tuple and Layer 2 Connection Parameters
You can now set the L2Conn option for a content switching virtual server. With the L2Conn option set, connections to the content switching virtual server are identified by the combination of the 4-tuple (
To set the L2Conn option for a content switching virtual server by using the CLI
At the command line, type the following commands to configure the L2Conn parameter for a content switching virtual server and verify the configuration:
- set cs vserver \ -l2Conn (**ON** | **OFF**) - show cs vserver \
Example
> set cs vserver mycsvserver -l2Conn ON Done > show cs vserver mycsvserver mycsvserver (192.0.2.56:80) - HTTP Type: CONTENT State: UP . . . . . . L2Conn: ON Case Sensitivity: ON . . . . . . Done >
To set the L2Conn option for a content switching virtual server by using the GUI
- Navigate toTraffic Management > Content Switching > Virtual Servers, and open a virtual server.
- InAdvanced Settings, selectTraffic Settings, and then selectLayer 2 Parameters.
