hi all,

1. i had used diffrent formate to send data .
//char *request = "GET https://202.189.252.134:80 HTTP/1.1\r\n";
 char *request = "GET / HTTP/1.1\r\nHost: 202.189.252.134\r\nConnection:
Close\r\n\r\n";
// char *request = "connect to server.";

for curl_easy_send. and it's return CURLE_OK. but getting problem in
curl_easy_recv
it's return proxy error :
HTTP/1.1 502 Proxy Error ( The Uniform Resource Locator (URL) does not use a
recognized protocol. Either the protocol is not supported or the request was
not typed correctly. Confirm that a valid protocol is in use (for example,
HTTP for aWeb request). )

2. when using
        char *request = "connect to server."; // for send buffer
and at server a application listning the port 443 and when get connect send
a response on same socket.
then getting response null curl_easy_recv. and CURLcode = CURLE_AGAIN

so please give me the solution where i am going wrong.
i think problem is related to send buffer text of curl_easy_send.

please help me
it's very urgent .

thanks

code:

int main(int argc, char* argv[])

      wait_on_socket(sockfd, 1, 60000L);
      res = curl_easy_recv(curl, buf, 1024, &iolen);

      if(CURLE_OK != res)

        break;
   }
   if(CURLE_AGAIN ==res)

   if(CURLE_OK == res)
   puts(buf);
   }

   puts(errorBuffer);
    /* always cleanup */
    curl_easy_cleanup(curl);

    }
 getch();
