how to validate the multi logins (different username and different password).
1. basically i want have two/more user accounts, each user account will have its individual limitation to open pages or edit data ect.
how can we achieve this ..?
2. is can i provide my own login page instead of this if we can where can i modify this..?
3. how can give the login authentication only for the first login rest of the pages would open but when tried to open individual pages it should as for the password how can i do this ..?

Hello Amar,
As per adboc you can able to send cookie to browser.
The below code will help you to parse the cookie from http request inside requst_notify()
#define HTTP_REQUEST_HEADER_BUFF_SIZE (512)#define HTTP_REQUEST_COOKIE_BUFF_SIZE (128)
BOOL fn_parse_cookies(NX_PACKET *packet_ptr, UCHAR *pchCookieBuff, uint uiBufferLen){ /** allocate header memory */ UCHAR *requestHeader = (UCHAR *) malloc(HTTP_REQUEST_HEADER_BUFF_SIZE); int bytes_copied, key_index_ctr = 0, ctr = 0, search_key_len = (int) strlen ("Cookie:"); UINT uiStatus; UCHAR ch; BOOL bCookieFound = FALSE; /* Retrieve data from packet pointed to by "packet_ptr". */ uiStatus = nx_packet_data_extract_offset (packet_ptr, 0, (VOID *) requestHeader, HTTP_REQUEST_HEADER_BUFF_SIZE, (ULONG *) &bytes_copied); /** Cookie: searching loop */ if (uiStatus == NX_SUCCESS) { while (ctr < bytes_copied) { /* Extract 8 chars form header and check for literal match of Cookie: */ while (ctr < bytes_copied && key_index_ctr < search_key_len) { ch = requestHeader[ctr]; // matching key characters with buffer characters if ("Cookie:"[key_index_ctr] != ch) { // match found, Cookie: found break; } ctr++; key_index_ctr++; } //loop - key matcher
// compare if ((key_index_ctr == search_key_len) == 1) { // Cookie: Start found bCookieFound = TRUE; break; } // if - key start found
// reset counter for future use key_index_ctr = 0; // Cookie: not yet found while (ctr < bytes_copied) { // loop until \r\n if (requestHeader[ctr] == '\n' && requestHeader[ctr - 1] == '\r') { // New Header: found ctr++; break; } ctr++; } // loop - next header search } // loop- cookie search } // if - header copied
uint coo_ctr = 0; if (bCookieFound == TRUE) { bCookieFound = FALSE; while (ctr < bytes_copied && coo_ctr < uiBufferLen) { if (requestHeader[ctr] == '\n' && requestHeader[ctr - 1] == '\r') { // all cookie copied pchCookieBuff[coo_ctr - 1] = '\0'; bCookieFound = TRUE; break; } pchCookieBuff[coo_ctr] = requestHeader[ctr]; ctr++; coo_ctr++; } }
/** free request header memory */free(requestHeader); return bCookieFound;}
UINT request_notify(NX_HTTP_SERVER *server_ptr, UINT request_type, CHAR *resource, NX_PACKET *packet_ptr)
{
/** allocate cookie buffer */ UCHAR *pchCookieBuff = malloc(HTTP_REQUEST_COOKIE_BUFF_SIZE);
/** parse cookie **/ fn_parse_cookies (packet_ptr, pchCookieBuff, HTTP_REQUEST_COOKIE_BUFF_SIZE);
/** release cookie buffer */free(pchCookieBuff);
// use cookie... :-)
