Hi, imagine I receive a TCP connection and I store the TCPSocket in a  
variable “io\_1”:

io\_1 = io

If I do “io\_1.peeraddr” I can see the remote address.

If latter the connection is closed by the peer and I do “io\_1.peeraddr”  
then I  
get an Exception because socket closed (ok).

Imagine later the _same_ connection is received and I store it in  
“io\_2”.  
Will “io\_1 == io\_2” return true? or should I compare “peeraddr” Array  
fields  
one by one (address, port…)?

Thanks.

No.

You can compare the Arrays without going field by field.
