in reply to checking for valid http links

If you just want to verify that the file is there, try a HEAD request instead of a GET request. If that gives you a false negative (it might, depending on the server), then set the max_size attribute of your LWP::UserAgent object to something like 512 bytes, so LWP will abort very quickly:
my $ua = LWP::UserAgent->new (max_size => 512); # note extra param my $tmpfile; foreach my $rev ("-", ('A'..'Z')) { $tmpfile = "$file$rev.$ext"; my $response = $ua->get("$path/$tmpfile"); # simpler interface ## you need to save $tmpfile here! last if $response->is_success; # better than yours }
