in reply to LWP::Simple - so they say!

Perhaps your webserver just doesn't respond to "HEAD" requests. Shit happens.

In that case, I'd call plain "GET" but you could abort halfway. You then will have to use a callback. See getprint (in LWP::Simple) as an example, which I have reproduced here:

sub getprint ($) { my($url) = @_; my $request = HTTP::Request->new(GET => $url); local($\) = ""; # ensure standard $OUTPUT_RECORD_SEPARATOR my $callback = sub { print $_[0] }; if ($^O eq "MacOS") { $callback = sub { $_[0] =~ s/\015?\012/\n/g; print $_[0] } } my $response = $ua->request($request, $callback); unless ($response->is_success) { print STDERR $response->status_line, " <URL:$url>\n"; } $response->code; }
You'd have to reproduce this but of course with a different callback... With die and eval BLOCK, it might just work.

    No need to abort with max_size

    #!/usr/bin/perl -- use strict; use warnings; use WWW::Mechanize; my $url = ''; my $ua = WWW::Mechanize->new( qw/ max_size 1 autocheck 1 show_progress 1 / ); eval { $ua->head($url); 1 } or $ua->get($url); print $ua->dump_headers; __END__
