有限公司nfigure persistence based on user-defined rules
Warning:
The use of Classic expressions for the persistence rule in the load balancing feature is deprecated. However Classic expressions are removed and no longer available for the filter rule on the Citrix ADC appliance release 13.1 onwards.
基于规则的持久性配置时,Citrix ADC appliance creates a persistence session based on the contents of the matched rule before directing the request to the service selected by the configured load balancing method. Later, it directs all requests that match the rule to the same service. You can configure rule based persistence for services of type HTTP, SSL, RADIUS, ANY, TCP, and SSL_TCP.
基于规则的坚持需要一个经典或default syntax expression. You can use a classic expression to evaluate request headers, or you can use a default syntax expression to evaluate request headers, Web form data in a request, response headers, or response bodies. For example, you can use a classic expression to configure persistence based on the contents of the HTTP Host header. You can also use a default syntax expression to configure persistence based on application session information in a response cookie or custom header. For more information on creating and using classic and default syntax expressions, seePolicies and Expressions.
The expressions that you can configure depend on the type of service for which you are configuring rule based persistence. For example, certain RADIUS-specific expressions are not allowed for protocols other than RADIUS, and TCP-option based expressions are not allowed for service types other than the ANY type. For TCP and SSL_TCP service types, you can use expressions that evaluate TCP/IP protocol data, Layer 2 data, TCP options, and TCP payloads.
Note: For a use case that involves configuring rule based persistence based on Financial Information eXchange (“FIX”) Protocol data transmitted over TCP, see有限公司nfiguring Rule Based Persistence Based on a Name-Value Pair in a TCP Byte Stream.
Rule based persistence can be used for maintaining persistence with entities such as Citrix SD-WAN appliances, Citrix SD-WAN plug-ins, cache servers, and application servers.
Note: On an ANY virtual server, you cannot configure rule-based persistence for the responses.
To configure persistence based on a user-defined rule, you first configure persistence as described in有限公司nfiguring Persistence Types That Do Not Require a Rule, and set the persistence type to RULE. You can then perform the following procedures. You can configure rule based persistence by using the configuration utility or the CLI.
To configure persistence based on user-defined rules by using the CLI
At the command prompt, type:
set lb vserver [-rule ][-resRule ]
Example:
set lb vserver vsvr_name –rule http.req.header("cookie").value(0).typecast_nvlist_t('=',';').value("server") set lb vserver vsvr_name –resrule http.res.header("set-cookie").value(0).typecast_nvlist_t('=',';').value("server")
To configure persistence based on user-defined rules by using the GUI
- Navigate to交通管理>Load Balancing>Virtual Servers, and open the virtual server.
- In the Persistence section, choose the persistence type that meets your requirement. The most suitable persistence type for the virtual server is available as option buttons. Other persistence types that are applicable to the specific virtual server type can be selected from the Others list.
Note
Prior to NetScaler release 12.0 build 56.20, all persistence types are available in a single Persistence drop-down list without any option buttons.
Example: Classic Expression for a Request Payload
The following classic expression creates a persistence session based on the presence of a User-Agent HTTP header that contains the string, “MyBrowser”, and directs any subsequent client requests that contain this header and string to the same server that was selected for the initial request.
http header User-Agent contains MyBrowser
Example: Default syntax Expression for a Request Header
The following default syntax expression does the same thing as the previous classic expression.
HTTP.REQ.HEADER(“User-Agent”).CONTAINS (“MyBrowser”)
Example: Default syntax Expression for a Response Cookie
The following expression examines responses for “server” cookies, and then directs any requests that contain that cookie to the same server that was selected for the initial request.
HTTP.RES.HEADER(“SET-COOKIE”).VALUE(0).TYPECAST_NVLIST_T(‘=’,’;’).VALUE(“server”)
