User session handling functions.

Code

function sess_write($key, $value) {
  global $user;

  // If the client doesn't have a session, and one isn't being created ($value), do nothing.
  if (empty($_COOKIE[session_name()]) && empty($value)) {

  }

  //  $result = db_query("SELECT sid FROM {sessions} WHERE sid = '%s'", $key);
  $result = dmemcache_get($key, 'session');

  // Prepare the information to be saved
  $info = new stdClass();
  $info->sid = $key;
  $info->uid = $user->uid;
  $info->cache = $user->cache;
  $info->hostname = $_SERVER["REMOTE_ADDR"];
  $info->session = $value;
  $info->timestamp = time();
  if (!$result) {

    // Only save session data when when the browser sends a cookie. This keeps
    // crawlers out of session table. This improves speed up queries, reduces
    // memory, and gives more useful statistics. We can't eliminate anonymous
    // session table rows without breaking throttle module and "Who's Online"
    // block.
