Hi David!!

Thanks for your reply, I didn't think about the very fact that I was 
actually trying to implement a tcp protocol on a web browser. Thanks for 
making me realize that. I guess now I can understand why that code in 
the "example" is not working for me beyond a point.. I was able to 
implement a chat application using UDP Datagrams and UDPSocket class in 
Ruby..
