}

output:

Main started
Server: is about to create socket
Client: about to create socket
Client: socket created
Client: creating streams
Server: socket created
Server: is listening
Server: Connection Established
Server: creating streams
Server: stream done
Server: reading the request
Client: stream done
Client: requesting
Client: requesting finished
Client: reading the respond

and it waits here forever!
