Match value types and their CPU impact

 

Hello Everybody,

 

I'd like to know if any of you have a little light on this:

 

I've been asked to come with an HMR to add a domain in the To header if the same domain comes in the host-part of the from header and the host-part of the To header is an IP address.

 

This was relatively simple to do:

 

header-rule
                name                           VerFrom
                header-name                    From
                action                         store
                comparison-type                case-sensitive
                msg-type                       any
                methods
                match-value
                new-value
                element-rule
                        name                           storeFrom
                        parameter-name                 From
                        type                           uri-host
                        action                         store
                        match-val-type                 any
                        comparison-type                case-sensitive
                        match-value                    ascs.domain.com
                        new-value
        header-rule
                name                           VerTo
                header-name                    To
                action                         store
