The actual computation takes about 4-5 minutes and I am using a RedHat Linux OS. I return some 1000 rows of data. Some 1000 rows of "The quick brown fox jumped over a lazy dog, and the lazy dog did nothing but bark", you can assume. So you are saying, in the child I store the result in a global variable($temp) and in the parent,I will have only one line that redirects the url to another cgi script with this $temp as parameter. i.e 

my $temp; # Global variable
if($pid)
{
print redirect();
exit;
}
else {
# call the computation function in child
}

But how will I know when $temp is populated completely? :(
