note 53445 added to ref.curl

Problems can occur if you mix CURLOPT_URL with a 'Host:' header in CURLOPT_HEADERS on redirects because cURL will combine the host you explicitly stated in the 'Host:' header with the host from the Location: header of the redirect response. In short, don't do this: $host = "www.dontusehostheaders.com"; $url = "http://$host/"; $headers = array("Host: $host"); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); Do this instead: $host = "www.dontusehostheaders.com"; $url = "http://$host/"; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); ---- Manual Page -- http://www.php.net/manual/en/ref.curl.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+53445 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+53445&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+53445&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+53445&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+53445&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+53445&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+53445&report=yes Search -- http://master.php.net/manage/user-notes.php
