Re: data gets corrupted (c sockets)

I would never imagine that even though the write function returns the
number of bytes
"written" to the file/socket/whatever, it doesn't mean that it's
really there right on time.

As I said in the first post, I suspected it had something to do with
buffering, but didn't
know how to check whether the data was delivered or not since I have
no interaction
with the browser on the client side.

Thank you.
