Hello,

here is proposal to add cookie handling to HTTPD. It is quite simple and
require LWIP_HTTPD_DYNAMIC_HEADERS to send the cookies. Also leaving all
processing up to user application. Application then needs to provide following
example functions.

#define SET_COOKIE_SIZE 48
char setCookie[SET_COOKIE_SIZE];

char *httpd_set_cookies(const void *connection, const char *uri) {
  LWIP_UNUSED_ARG(uri);

  if (connection == verifiedConn) {
    verifiedConn = NULL; // Clear verified connection
    snprintf(setCookie, SET_COOKIE_SIZE, HDR_HTTP_RES_SET_COOKIE
"id=%08X\r\n", authorizedConn.id);
    return setCookie;
  }
  return NULL;
}

void httpd_received_cookies(const void *connection, const char *cookies) {
  const char *sessionId = strstr(cookies, "id=");
  if (sessionId != NULL) {
     uint32_t value = strtol(sessionId+3, NULL, 16);
     if (value == authorizedConn.id) {
       authorizedConn.conn = (uint32_t *)connection;
     }
  }
}
