@s{quotedtext} @s{quotedtext} Perl's LWP module definitely sets the Content-Length header.  I would've been surprised if it didn't, since it is required by HTTP 1.0 and the HTTP 1.1 spec says clients 'SHOULD' set it.

After some struggle, I got the first JSON::RPC library at CPAN to work:
Code:
use JSON::RPC::Client;
use Data::Dumper;
 
my $client = new JSON::RPC::Client;

$client->ua->credentials(
   'localhost:8332', 'jsonrpc', 'my rpcusername' => 'my rpcpassword'   # Replace with real user/pass
    );
my @foo = $client->ua->credentials('localhost:8332', 'jsonrpc');
print "@foo\n";

my $uri = 'http://localhost:8332/';
my $obj = {
    method  => 'getinfo',
    params  => [],
 };
 
my $res = $client->call( $uri, $obj );
 
if($res){
    if ($res->is_error) {
        print "Error : ", $res->error_message;
    }
    else {
        print Dumper($res->result);
    }
}
else {
    print $client->status_line;
}
The struggle was setting the realm to 'jsonrpc' (it is fussy about that).  I'll document that on the wiki.
