Request / Reponse iRules

 

If I have an iRule that looks at HTTP Requests as in:

 

 

when HTTP_REQUEST {

 

some request logic here...

 

}

 

 

and another iRule that looks at HTTP Responses as in:

 

 

when HTTP_RESPONSE {

 

some response logic here...

 

}

 

 

Is it better to combine these into a single rule if possible? e.g. is it better performance-wise, etc.

 

 

What is the rule-of-thumb in this case?

 

 

Thank You.

    The main decision point is manageability on your part. If the logic in the two rules are related, then it's probably best to combine them into a single iRule. If they are not and you will use them in multiple contexts, then it might be best to keep them separate.

     

     

    There is a very minimal configuration overhead to split it apart into multiple iRules as there are two configuration objects instead of one, but it's nothing that should be of a concern to you regarding runtime performance.
