  From  The  Free  On-line  Dictionary  of  Computing  (13  Mar  01)  [foldoc]: 
 
  stateless 
 
  A  stateless  {server}  is  one  which  treats  each  request  as  an 
  independent  transaction,  unrelated  to  any  previous  request. 
  This  simplifies  the  server  design  because  it  does  not  need  to 
  allocate  storage  to  deal  with  conversations  in  progress  or 
  worry  about  freeing  it  if  a  client  dies  in  mid-transaction.  A 
  disadvantage  is  that  it  may  be  necessary  to  include  more 
  information  in  each  request  and  this  extra  information  will 
  need  to  be  interpreted  by  the  server  each  time. 
 
  An  example  of  a  stateless  server  is  a  {World-Wide  Web}  server. 
  These  take  in  requests  ({URL}s)  which  completely  specify  the 
  required  document  and  do  not  require  any  context  or  memory  of 
  previous  requests. 
 
  Contrast  this  with  a  traditional  {FTP}  server  which  conducts 
  an  interactive  session  with  the  user.  A  request  to  the  server 
  for  a  file  can  assume  that  the  user  has  been  authenticated  and 
  that  the  current  directory  and  transfer  mode  have  been  set
