Quick (hopefully) question about clearing stick table entry

[Franks Andy (IT Technical Architecture Manager)]

Hi all,
  Is there a way to clear a stick table entry (using socat obviously) by 
referring to the individual 'reference' id given at the beginning of the entry, 
e.g. "0x7faef417d3ec" ?
Looking at the manual it seems the clearing function is based on key (ip in my 
case) or data field - server id etc. I could use the key, but I'm not sure this 
will always be individual - I may not always use "stick on src".
Maybe I'm confused :) and IP key IS the best.
Thanks
Andy
