Here is one of my final objectives at PHP introductory course ot
O'Reilly. The strange thing that setting a cookie in that program
les13uadownload.php doesn't work. I don't have a clue - sometimes in
other programs when I run them they set cookies and sometimes not. To
see the full functionality of this "program" I had to set cookie
sevendays in another program. Please check where is my bug. Thanks in
advance, Grega from Slovenia
