what about this one? 

[root@ve10:Active] config  b virtual bar list
virtual bar {
   destination 172.28.19.79:80
   ip protocol 6
   rules myrule
   profiles {
      http {}
      tcp {}
   }
}
[root@ve10:Active] config  b rule myrule list
rule myrule {
   when HTTP_REQUEST {
   if { [HTTP::host] eq "mycompany.com" } {
      HTTP::collect [HTTP::header "Content-Length"]
   }
}
when HTTP_REQUEST_DATA {
   log local0. "[HTTP::payload]"
   if { [HTTP::header Expect] eq "100-continue" } {
      HTTP::respond 100 noserver
   } else {
      HTTP::respond 200 noserver
   }
}
}
