note 67262 added to function.setcookie

I just discovered that IE6 (6.0.2800.1106 at least) seems to have difficulties accepting cookies when the subdomain part of the URL is longer than 10 characters. This applies to automatic sessionid's as well (that's how I found out). So: Setting a cookie on a site named http://examples.test.com/ will work, doing the same on http://my_examples.test.com will fail (or at least, failed for me). Tested it by snooping the outgoing traffic from the client: the GET request lacks the COOKIE: header in the last case. A closer inspection revealed that the cookie was never accepted in the first place: when the subdomain is longer than 10 characters, no cookiefile is created in the temporary internet files directory. Temporary cookies (like the PHP sessionid) have the same problem. Firefox and Konqueror have no problem with this. ---- Server IP: 194.109.193.119 Probable Submitter: 84.41.220.121 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/function.setcookie.php Edit -- http://master.php.net/note/edit/67262 Del: integrated -- http://master.php.net/note/delete/67262/integrated Del: useless -- http://master.php.net/note/delete/67262/useless Del: bad code -- http://master.php.net/note/delete/67262/bad+code Del: spam -- http://master.php.net/note/delete/67262/spam Del: non-english -- http://master.php.net/note/delete/67262/non-english Del: in docs -- http://master.php.net/note/delete/67262/in+docs Del: other reasons-- http://master.php.net/note/delete/67262 Reject -- http://master.php.net/note/reject/67262 Search -- http://master.php.net/manage/user-notes.php
