note 51548 added to ref.session

Search engines in general don't support cookies, and they don't do well with SIDs in the query string. If you use sessions, especially URL-based sessions, and want your site to be search engine friendly, the following works well: <?php $br = get_browser(); if (!($br->crawler)) { // any session-related code goes here } else { // whatever your page needs to work without sessions } ?> To use the function get_browser() you may need to install browscap.ini. See the documentation for get_browser() for more info. ---- Manual Page -- http://www.php.net/manual/en/ref.session.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+51548 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+51548&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+51548&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+51548&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+51548&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+51548&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+51548&report=yes Search -- http://master.php.net/manage/user-notes.php
