I’m making a simple http page-requester in C. It uses sockets to send HTTP/1.0 GET requests to hosts, and parses the answer to effectively download the html file.
However, when i send a request like this:

GET http://stackoverflow.com/questions HTTP/1.0
User-Agent: myRequester/1.0

It returns this

HTTP/1.1 200 OK
Cache-Control: private
Content-Type: text/html; charset=utf-8
Date: Mon, 19 Dec 2011 15:28:08 GMT
Content-Length: 54362
Connection: close

But no body content.

Yes, I’ve put CRLF on the end of every line and a blank line at the end.
I use only one socket through one connection. And i also have to stick to HTTP/1.0.

    The most likely explanation is that the server is actually sending a body but you are not reading all of it. Most networking systems do not necessarily return all of the response in one function call, because they see it useful that what data is available immediately is returned immediately, even if more is expected.

    The Unix system call recv returns zero when the connection has ended. You should keep calling it until you get zero or an error.
