This is the "old fashioned" way to do it. Instead, you are probably better off using the CGI.pm way, which is documented as such:      use CGI qw [ -nph :standard ]; The '-nph' triggers a header equivalent to the aforementioned 'nph-' prefix on the CGI. There are several alternative methods, plus other discussion, in the CGI documentation under 'NPH'.

Of course, you will have to unbuffer STDOUT for full effect, as with:      $|++; As a further note, make sure the HTML you are sending to the browser can be displayed immediately. Under Netscape, for example, a table will not display until it is fully loaded. If you keep sending table data ad infinitum, the table will never display. This also applies to other tags including, but not limited to, UL and OL.
