bind cr vserver

Binds a cache redirection policy to a cache redirection virtual server.

Synopsys

bind cr vserver <name> [-lbvserver <string> | (-policyName <string> [-priority <positive_integer>] [-gotoPriorityExpression <expression>] [-type <type>] [-invoke (<labelType> <labelName>) ] ) | <targetVserver>]

Arguments

name

Name of the cache redirection virtual server to which to bind the cache redirection policy.

lbvserver

Name of the virtual server to which content is forwarded. Applicable only if the policy is a map policy and the cache redirection virtual server is of type REVERSE.

policyName

Name of the cache redirection policy that you are binding.

targetVserver

Name of the virtual server to which content is forwarded. Applicable only if the policy is a map policy and the cache redirection virtual server is of type REVERSE.

priority

An unsigned integer that determines the priority of the policy relative to other policies bound to this cache redirection virtual server. The lower the value, higher the priority. Note: This option is available only when binding content switching, filtering, and compression policies to a cache redirection virtual server.

Minimum value: 0

gotoPriorityExpression

Expression or other value specifying the next policy to be evaluated if the current policy evaluates to TRUE. Specify one of the following values:

* NEXT ~V Evaluate the policy with the next higher priority number.

* END ~V End policy evaluation.

* USE_INVOCATION_RESULT ~V Applicable if this policy invokes another policy label. If the final goto in the invoked policy label has a value of END, the eval* USE_INVOCATION_RESULT ~V Applicable if this policy invokes another policy label. If the final goto in the invoked policy label has a value of END, the eval

uation stops. If the final goto is anything other than END, the current policy label performs a NEXT.

* A default syntax expression that evaluates to a number.

If you specify an expression, the number to which it evaluates determines the next policy to evaluate, as follows:

* If the expression evaluates to a higher numbered priority, the policy with that priority is evaluated next.

* If the expression evaluates to the priority of the current policy, the policy with the next higher numbered priority is evaluated next.

* If the expression evaluates to a priority number that is numerically higher than the highest numbered priority, policy evaluation ends.

An UNDEF event is triggered if:

* The expression is invalid.

* The expression evaluates to a priority number that is numerically lower than the current policy~Rs priority.

* The expression evaluates to a priority number that is between the current policy~Rs priority number (say, 30) and the highest priority number (say, 100), b

ut does not match any configured priority number (for example, the expression evaluates to the number 85). This example assumes that the priority number incr

ements by 10 for every successive policy, and therefore a priority number of 85 does not exist in the policy label.

type

policies, because content switching policies are evaluated only at request time.

Possible values: REQUEST, RESPONSE, ICA_REQUEST

invoke

application firewall, transform, integrated cache, rewrite, responder, and content switching).
