  OK. Better it would be to generate something random. No problem.

  I'm more than amazed. Never thought it could be so simple !
  In fact, if I save the page and submit it again from c:\something, referer 
will be blank. When it comes from my site, it comes with the complete URL.

  Guess I should require that referer would be myself, I mean, my own site.
  
  But, I'm still holding myself to believe that this is so simple like that...
  
  ThanXs !
