[Tutor] creating a server

[nathan tech]

Exactly!

that's what part of my question was, really :) how does one go about 
verifying all data was received?

recv(2000000)

seems a bit ludicrous to me and besides, what you don't want to do is 
receive an object and then half of the next one, too!

Thanks
