Header insert for lb server ip and tcp port

All,

 

Not having any issues with the irule outputting the last 2 digits of the server tcp ports. Client changed the ports on the server end, so I need the first 2 digits. See below.

 

Thanks,

Last Digits work great

 

rule myrule {

 

when HTTP_RESPONSE {

 

scan [IP::remote_addr] {%*d.%*d.%d.%d} c d

 

HTTP::header insert "X-Who-A" "AN-$c.$d-[TCP::remote_port]"

 

}

 

}

 

 

Tried this logic for the first 2 digits in the header insert. No dice!

 

rule myrule {

 

when HTTP_RESPONSE {

 

scan [IP::remote_addr] {%*d.%*d.%d.%d} a b

 

HTTP::header insert "X-Who-A" "AN-$a.$b-[TCP::remote_port]"

 

}

 

}
