I have a temporary image file that is generated by a script It then is loaded by the browser in the output of the script (e.g. <img src="temp_Ad934C.gif">). However, it needs to be deleted after it is shown. I could do this by replacing the filename of the image by a script that deletes the file after it is run (e.g. <img src="deleteaftershown.pl?temp_Ad934C.gif">) but this is too sensitive for hazardous attacks. I tried to use an END block that is executed after the main script is executed and it deletes the tempfile after 5 seconds. However when running this, the browser first waits 5 seconds before displaying the page. This is obvious as the script is still running. How can I force Perl to end the connection with the browser but keep running the script? 
END {
    #delay delete tempfile
    my $oldtime = (time + 5);
        my $i=1;
    while ($i==1) {
            if (time > $oldtime) {
                       $i=0;
                    if($tempfile ne "") {
                            unlink($tempfile)
                    }

            }
    }
}
