    Hi,
    Here is what am I trying to do:
    I want my page to refresh it self every 5 seconds, but only if some file has changed in last 5 seconds. I can check that easy with Perl script, but problem begins when that file hasn't changed and in that case I don't want my page to refresh, so I would just exit the script with out printing anything to html.
    And in that case this error appears: "Premature end of script headers"
    How can I fix that?

    Scrip is called by html in this way:

    <meta http-equiv="Refresh" content="5; URL=http://www.upitnik.net/cgi-bin/test.pl">

    If script does nothing when called, would above line call script every 5 seconds ?
    If not, how could I do this what am I trying to do?

    Tell your script to overwrite the line -> <meta http-equiv="Refresh" content="5; URL=http://www.upitnik.net/cgi-bin/test.pl"> so it doesn't refresh any longer.
    The initial state when your script is called, tell it to print "<meta http-equiv="Refresh" content="5; URL=http://www.upitnik.net/cgi-bin/test.pl">"
