Hi,

 

Thanks for the solution and I am planning to use Policy instead of irule for new requirement to check the benefits.

 

Looking for clarification on Variable option;

 

1.Set Variable named should be specific to any name? because i see the conditions equal to pool member.

2.Is there any option apart from Variable because i see below guidelines when using TCL command substitution;

 

  • Memory and CPU capacity determine a maximum number of rules for active policies; however, excessive Tcl command substitutions can degrade performance.
  • Tcl command substitutions are primarily intended for reading and returning data.

 

Thank You.

Hi,

Here my answers:

 

.Set Variable named should be specific to any name? because i see the conditions equal to pool member.

Yes, it is disposable anyway.

 

2.Is there any option apart from Variable because i see below guidelines when using TCL command substitution;

I can't see another than built-in way to send to a node directly. (the "Forward traffic to node" action)

I just can say that approach is a workaround to reach the similar we can do in iRule.

I usually use "Set variable" mixed to an iRule, to control HTTP redirect 301, for example.

 

Regards.
