USR2 only fires when you do it yourself, e.g.
kill -USR2 `cat /var/run/httpd.pid`
or under linux
killall -USR2 httpd
However, if you want to change based on mod time, then one way to do it
would be as follows (THIS CODE IS UNTESTED!!!).
in the handler/CGI that USES the 700k doc:
my $big_doc = My::get_big_doc();
and in startup.pl you can say:
package My;
my $big_doc = undef;
my $mod_time = 0;
my $big_file = '/path/to/big/file';
sub get_big_doc {
if (defined $big_doc and -M $big_file < $mod_time) {
return $big_doc;
} # implicit else
($big_doc, $mod_time) = some_complex_operation();
return $big_doc;
}
sub some_complex_operation {
# read in $big_doc and its $mod_time
return ($big_doc, $mod_time);
}
HTH!
