I have a SUN environment running an WebLogic that communicates w/a 3rd party running IIS. When the IIS site goes down (frequently), I am stuck with sockets in an ESTABLISHED state, and cannot seem to figure out how to avoid this.

First of all, i'm no TCP/IP-wiz, so forgive me if this is a stupid question.
I've been messing around with filetransfer using sockets, and there is one thing that confuses me.

Hello,
Our software is using a TCP socket (AF_INET, SOCK_STREAM) to communicate with an Ethernet device. When we send a message, the message object writes itself in full onto the socket's stream buffer before the software invokes send() from socket.h.

So I believe this is what I should use. The problem is that all the... (2 Replies)

my $client = Mojo::IOLoop::Client->new;
$client->on(connect => sub {
my ($client, $handle) = @_;
...
});
$client->on(error => sub {
my ($client, $err) = @_;

DESCRIPTION
Mojo::IOLoop::Client opens TCP connections for Mojo::IOLoop.
EVENTS
Mojo::IOLoop::Client can emit the following events.
"connect"
$client->on(connect => sub {
my ($client, $handle) = @_;
...
});
Emitted safely once the connection is established.
"error"

"reactor"
my $reactor = $client->reactor;
$client = $client->reactor(Mojo::Reactor::Poll->new);
Low level event reactor, defaults to the "reactor" attribute value of the global Mojo::IOLoop singleton.

"connect"
$client->connect(address => '127.0.0.1', port => 3000);

"handle"
Use an already prepared handle.
"local_address"
