Sensitive Cookie Missing 'HTTPONLY' Attribute

Based on what I'm seeing this is may be a false Positive, right?doesn't audit have log to prove what they found?

anyway, to prevent adding duplicate httponly, you may check whether there is before adding.

e.g.

[root@ve10:Active] config  b virtual bar list
virtual bar {
   snat automap
   pool foo
   destination 172.28.19.79:80
   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 {
   set ck [HTTP::header values "Set-Cookie"]
   HTTP::header remove "Set-Cookie"
   foreach acookie $ck {
      if { [string tolower $acookie] contains "httponly" } {
         HTTP::header insert "Set-Cookie" "${acookie}"
      } else {
         HTTP::header insert "Set-Cookie" "${acookie}; HttpOnly"
      }
   }
}
}
