16. Sessions
Error:
Drupal doesn't store session information the first time an anonymous user visits a site. This is to keep evil web crawlers and robots from flooding the sessions table. As a developer, this means you cannot store session information for the first visit from an anonymous user.
Correction:
Drupal doesn't usually store session information the first time an anonymous user visits a site. This is to keep evil web crawlers and robots from flooding the sessions table. As a developer, you should try to avoid storing session information for the first visit from an anonymous user.
Description of the Error:
Drupal will store session information for the first page view from an anonymous visitor if data has been stored in $_SESSION. See http://api.drupal.org/api/function/sess_write/6.
