Header insert for lb server ip and tcp port

e.g.

[root@ve10:Active] config  b virtual bar list
virtual bar {
   snat automap
   pool foo
   destination 172.28.19.252:80
   ip protocol 6
   rules myrule
   profiles {
      http {}
      tcp {}
   }
}
[root@ve10:Active] config  b pool foo list
pool foo {
   members 200.200.200.101:80 {}
}
[root@ve10:Active] config  b rule myrule list
rule myrule {
   when HTTP_RESPONSE {
  scan [IP::remote_addr] {%d.%d.%d.%d} a b c d
  HTTP::header insert "X-Who-A" "AN-$c.$d-[TCP::remote_port]"
}
}
[root@ve10:Active] config  curl -I http://172.28.19.252
HTTP/1.1 200 OK

you may avoid using a and b variables by using asterisk (*).

[root@ve10:Active] config  b rule myrule list
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]"
}
}

Perfect, works great! Thanks for your help!

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]"

 

}

 

}

I see the issue, a and be are * out.
