Hi All,
I have used the following code to get web page from web server.

I found I can send the http request to the web server succesfully.
the err no = 0.
However, I found I cannot receive any byte from the web server after
posting the HTTP request!
What mistake had I made?
What is the correct way to receive byte by using the function
NetLibReceive?
Thanks for your advice!
