in thread how can I execute an html file from Perl

I think what you are now saying is that, given an absolute path on the filesystem, convert that to a URL and print it. In which case something like this (untested) should do:

(my $url = $out_file) =~ s#$ENV{DOCUMENT_ROOT}#http://$ENV{SERVER_NAME
+}#;
print "Go to $url now for prizes!\n";
