    text
    copied!<p>I am having problems receiving data from a remote server. It seems that I can send an HTTP request to a host such as <a href="http://www.google.com" rel="nofollow">http://www.google.com</a>, but I can't get a reply. I'm sending the host a HTTP 1.0 request that is formatted as such:</p> <p>GET / HTTP/1.0<br> Host: www.google.com<br> Connection: close</p> <p>Here are is part of the proxy code:</p> <pre><code> //Parse Request Buffer HttpRequest req; req.ParseRequest(request.c_str(), request.length()); //Format Data to be Sent: req.AddHeader ("Connection", "close"); // add connection close headers req.SetVersion ("1.0"); // set http 1.0 flag char *requestBuf = new char [req.GetTotalLength()]; req.FormatRequest(requestBuf); //Get host IP by name struct hostent *host; host = gethostbyname(req.GetHost().c_str()); //Setup remote address structure struct sockaddr_in remoteAddr; remoteAddr.sin_family = AF_INET; remoteAddr.sin_port = htons(req.GetPort()); remoteAddr.sin_addr = *((struct in_addr *)host-&gt;h_addr); //create new socket for remote server int remoteSock = socket(AF_INET, SOCK_STREAM, 0); if(remoteSock &lt; 0) { perror("Socket Error"); //return -1; } //connecting to remote server if(connect(remoteSock, (struct sockaddr *)&amp;remoteAddr, sizeof(remoteAddr)) &lt; 0) { perror("Connect Error"); //return -1; } cout.flush() &lt;&lt; requestBuf &lt;&lt; endl; //send request to remote server if(send(remoteSock, requestBuf, sizeof(requestBuf), 0) &lt; 0) { perror("Write Error"); //return -1; } //receive reply from server char *recBuf = new char [1024]; int bufSize = 1024; int readSize; while(1) { readSize = read(remoteSock, recBuf, bufSize); //Read from Remote Server cout.flush() &lt;&lt; recBuf &lt;&lt; endl; if(readSize &lt;= 0) //If the requestBuf not filled, nothing left to send to client break; write(clientSock, recBuf, readSize); //write reply to Client } close(remoteSock); </code></pre> <p><br> The cout.flush() of recBuf outputs nothing.<br> Any ideas on whats going on?</p>
