Htttp post header format

Legacy Open AT
1

I’ve been trying to send data to our Vodafone server with HTTP POST but i get the following response from the server:

http session channel created
[HTTP] new request GET weather.vodafonernd.com/post.php HTTP/1.1 @ 180ec7
a0
[HTTP] req parsed URL: /post.php at weather.vodafonernd.com
[HTTP] connect to host: weather.vodafonernd.com:80
HTTP data channel created
http_ClientTestDataHandler: Start
http_ClientTestDataHandler: WIP_CEV_WRITE
http_ClientTestDataHandler: 160 bytes written
http_ClientTestDataHandler: WIP_CEV_READ
http_ClientTestDataHandler: Status=400
http_ClientTestDataHandler: Reason=“Bad Request ( The HTTP request includes a no
n-supported header. Contact your ISA Server administrator. )”
[WIP] closing HTTP_DATA 0x180ec7a0
[HTTP] destroy request @ 180ec7a0
[WIP] closing HTTP_CONTROL 0x180ec560
[WIP] closing TCPCLIENT 0x180dcb80

The server says my HttP request includes a non-supported header but i followed the format specified in the Open AT IP dev. guide:

static s32 http_Client(void)
{
s32 ret = 0;

// HTTP Session creation
// ---------------------------
http_ClientTestCtx.CnxChannel = wip_HTTPClientCreate(
                                    NULL,  // no handler
                                    NULL  // no context
                                    );

  if (http_ClientTestCtx.CnxChannel == NULL)
  {
     TRACE(( 2, "cannot create http session channel\n" ));
     //adl_atSendResponse ( ADL_AT_UNS, "cannot create http session channel\r\n" );
     adl_atSendResponsePort ( ADL_AT_RSP, ADL_PORT_UART1, "\r\ncannot create http session channel\r\n");
     ret = -1;
  }
  else {
	  adl_atSendResponsePort ( ADL_AT_RSP, ADL_PORT_UART1, "\r\nhttp session channel created\r\n");


     // HTTP POST command
      		    http_ClientTestCtx.DataChannel = wip_getFileOpts(
      		                                         http_ClientTestCtx.CnxChannel,  // session channel
      		                                         HTTP_STR_URL,                   // URL to receive the data
      		                                         http_ClientTestDataHandler,     // data handler
      		                                         &http_ClientTestCtx,            // context
      		                                         WIP_COPT_HTTP_METHOD,  WIP_HTTP_METHOD_POST,
      		                                         // request headers
      		                    WIP_COPT_HTTP_HEADER, "Host","weather.vodafonernd.com",
      		              WIP_COPT_HTTP_HEADER, "Content-Type",":application/x-www-form-urlencoded",
      		                  WIP_COPT_HTTP_HEADER, "Accept",":text/html",
      		          WIP_COPT_HTTP_HEADER, "User-Agent", "Weather",	                                                 WIP_COPT_HTTP_HEADER, "Referer:","http://weather.vodafonernd.com/testpost.com",
      		                                         WIP_COPT_END);

      		    if (http_ClientTestCtx.DataChannel == NULL)
      		    {
      		      TRACE(( 2, "cannot create http data channel\n" ));
      		      //adl_atSendResponse ( ADL_AT_UNS, "cannot create http data channel\r\n" );
   adl_atSendResponsePort ( ADL_AT_RSP, ADL_PORT_UART1, "\r\ncannot create http data channel\r\n");
      		      wip_close( http_ClientTestCtx.CnxChannel);
      		     // ret =-1;
      		    }
      		    else
  adl_atSendResponsePort ( ADL_AT_RSP, ADL_PORT_UART1, "\r\nHTTP data channel created\r\n");
 }
  		    return(ret);

}

How can i solve this problem ?
