12. The method of claim 1, wherein at least one of the first action and the second action specifies rewriting a URL contained in an HTTP response.
13. The method of claim 1, wherein at least one of the first action and the second action comprises an object-oriented expression.
14. The method of claim 1, wherein step (c) comprises receiving, via the configuration interface, information identifying a second action for the policy, the second action to be taken if an expression of the policy is undefined.
15. The method of claim 1, wherein step (c) comprises receiving, via the configuration interface, information identifying a second action for the policy, the second action to be taken if a rule of the policy is undefined.
16. The method of claim 1, wherein step (c) comprises receiving, via the configuration interface, information identifying a second action for the policy, the second action to be taken if the first action of the policy is undefined.
17. In an appliance, a method of applying a policy specifying an action to be taken in the event an element of the policy is undefined, the method comprising:
(a) identifying, by an appliance, a policy to evaluate with respect to a payload of a received packet stream, the policy specifying (i) an expression, (ii) a first action to be taken based on an evaluation of the expression and (iii) a second action to be taken if an element of the policy is undefined;
(b) determining, by the appliance, an element of the policy is undefined with respect to the payload; and
(c) taking, by the appliance in response to the determination, the second action.
18. The method of claim 17, wherein step (b) comprises evaluating an object-oriented expression.
19. The method of claim 17, wherein step (b) comprises evaluating an expression having an object class and a member of the object class.
20. The method of claim 17, wherein step (b) comprises determining, by the appliance, the expression is undefined with respect to the packet stream.
21. The method of claim 17, wherein step (b) comprises determining, by the appliance, a rule of the policy is undefined.
22. The method of claim 17, wherein step (b) comprises determining, by the appliance, the first action of the policy is undefined.
23. The method of claim 17, wherein step (c) comprises taking no action.
24. The method of claim 17, wherein step (c) comprises blocking transmission of the packet stream from the appliance.
25. The method of claim 17, wherein step (c) comprises performing one of: load balancing, content switching, application security, application delivery, network acceleration, or application acceleration.
26. The method of claim 17, wherein step (c) comprises rewriting a portion of the payload of the packet stream.
27. The method of claim 17, wherein step (c) comprises rewriting a URL contained in an HTTP response.
28. An appliance which enables users to specify an action to be taken in the event an expression contained in a policy cannot be evaluated by the appliance, the appliance comprising:
a packet processor which receives a packet stream; and
a policy engine which identifies a policy to evaluate with respect to the payload of the received packet stream, the policy specifying (i) an expression, (ii) a first action to be taken based on an evaluation of the expression and (iii) a second action to be taken if the expression is not successfully evaluated; determines the expression cannot be successfully evaluated with respect to the packet stream; and takes the second action.
29. The system of claim 28, wherein the policy engine evaluates an object-oriented expression.
30. The system of claim 28, wherein the policy engine evaluates an expression having an object class and a member of the object class.
31. The system of claim 28, wherein the second action comprises no action.
32. The system of claim 28, wherein the second action comprises blocking a portion of a packet stream.
33. The system of claim 28, wherein at least one of the first action and second action specifies a function directed to at least one of: load balancing, content switching, application security, application delivery, network acceleration, and application acceleration.
34. The system of claim 28, wherein at least one of the first action or the second action specifies rewriting a portion of the payload of the packet stream.
35. The system of claim 28, wherein at least one of the first action or the second action specifies rewriting a URL contained in an HTTP response.
36. The system of claim 28, wherein the policy engine determines the expression is undefined with respect to the packet stream.
37. The system of claim 28, wherein the policy engine determines a rule of the policy is undefined with respect to the packet stream.
38. The system of claim 28, wherein the policy engine determines the first action is undefined with respect to the packet stream.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
