LWP::Head does not give me the last_modified value

[Tulan W. Hu]

I just upgraded from perl 5.6 to perl 5.8.2
and installed libwww-5.76.
I'm wondering what I did wrong to make
LWP::Head gives me undefined value in the last_modified field.
Any suggestions?

My test program is
use LWP::UserAgent;
use LWP::Debug qw(+);

my $ua = new LWP::UserAgent;
my $cmd = "http://localhost/file.html";
my $req = new HTTP::Request('HEAD', $cmd);

my $res = $ua->request($req);

#check the outcome
if ($res->is_success) {
print "Connect successful\n";
print $res->message . "\n" . $res->code . "\n";
print $res->as_string . "\n";
my $ref = $res->last_modified;
print "last_modified $ref\n";
}else {
print "Error: " . $res->status_line . "\n";
}

I take it that used to work on 5.6 ?
Your script certainly works for me (giving the last modified time) on
the following:
1) perl 5.6.1 (AS build 626) on Win2k
2) perl 5.8.2 (AS build 808) on Win2k
3) perl 5.8.0 on linux (mdk-9.1)

I'm also running libwww-5.76.

What operating system do you have ?

Cheers,
Rob

I have solaris 8. I tested more on the script after I posted the question.
I found out it maynot be the problem on my script.
Maybe some web servers just do not return the last_modified field.
Is this true? Maybe I shall ask this question on another group or
some guru here have the answer for me?

Thanks!
