AVB webserver can not support IE browser

[oyhp052]

Hello,
does anybody has developped AVB webserver by reference to the app_simple_webserver ?
I have designed an AVB webserver, it can support firefox and chrome browser successful, but can not support IE browser.

Code: Select all

//***************** portions of code *******************************


// Receive a HTTP request
void httpd_recv(chanend tcp_svr, xtcp_connection_t *conn)
{
  struct httpd_state_t *hs = (struct httpd_state_t *) conn->appstate;
  char data[XTCP_CLIENT_BUF_SIZE];
  int len;
  
  // Receive the data from the TCP stack
  len = xtcp_recv(tcp_svr, data);
  
  // If we already have data to send, return
  if ( hs == NULL || hs->dptr != NULL)
    {
      return;
    }
  
  // Otherwise we have data, so parse it
  parse_http_request(hs, &data[0], len);
  
  // If we are required to send data
  if (hs->dptr != NULL)
    {
      // Initate a send request with the TCP stack.
      // It will then reply with event XTCP_REQUEST_DATA 
      // when it's ready to send
      xtcp_init_send(tcp_svr, conn);
    }
}

...

// Parses a HTTP request for a GET
void parse_http_request(httpd_state_t *hs, char *data, int len)
{
	static int ack_cnt = 0 ;
	int http_valid_data_flag = 0;
	static int dynamic_test_cnt = 0;
	static int status_test_cnt = 0;
	static char chan_num, val;


  // Return if we have data already
  if (hs->dptr != NULL)
    {
      return;
    }

  // Test if we received a HTTP GET request
  if (strncmp(data, "GET / HTTP", 10) == 0)
    {
#if DEBUG_PARSE_HTTP
	  printstrln("receive GET webpage");
#endif

	  load_data_in_flash(AVB_WPAGE_START_ADDR, AVB_WPAGE_LENGTH, wpage_buf);

	  hs->dptr = &wpage_buf[0];
	  hs->dlen = AVB_WPAGE_LENGTH;
   }
  else if (strncmp(data, "POST /POWER", 11) == 0)
  {
#if 1
	printstrln("receive POST /POWER");
	for(int i=0; i<len; i++)
	  printchar(data[i]);
#endif
     
    ...
  }
    ...

//******************************************************************

When debug the program and use of firefox or chrome to click the web buttom(Phantom power), it print as follws:
1.firefox browser

(Request-Line):POST /POWER HTTP/1.1
User-Agent:Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0)
Host:192.1.4.110
Content-Type:application/octet-stream
Content-Length:11
Accept:*/*



88390065 21


2.chrome browser

(Request-Line):POST /POWER HTTP/1.1
Accept-Language:zh-CN,zh;q=0.8
Host:192.1.4.110
User-Agent:Mozilla/5.0 (Windows NT 5.1) AppleWebKit/537.31 (KHTML, like Gecko) Chrome/26.0.1410.64

Safari/537.31
Connection:keep-alive
Referer:...
Origin:...
Accept-Encoding:gzip,deflate,sdch
Accept-Charset:GBK,utf-8;q=0.7,*;q=0.3
Content-type:application/x-www-form-urlencoded
Content-Length:11
Accept:*/*


88390065 21

However, when I use IE browser to visit and click the web's buttom, it print only HTTP packet header as follows:

(Request-Line):POST /POWER HTTP/1.1
Host:192.1.4.110
Cookie:OUTFOX_SEARCH_USER_ID=-80099848@115.204.95.140
Cache-Control:no-cache
Connection:Keep-Alive
Content-Length:11
Accept:*/*


But it can not receive and print the valid data(88390065 21), I don't know why. Does any one can help me to anaylze this problem or give me some suggestion ? It seems that the tcp stack can not parse the IE browser's http packet, right ?
