I would in cgi to have a perl program write a html script and with a sleep command in the perl code after the html is written to wait then rewrite another html script out to cgi screen. I know I could write a html out with a javascript timer to after a time bring up the second html screen. But in this case the perl cgi program i want to be one controling how long the wait is before the second html screen replaces the first. Right now the second screen just show under the first one the browser instead of replacing it. ? Can this be done and if so how do i get the second to replace the first
