note 76758 added to function.header

I spent a long time trying to determine why Internet Explorer 7 wasn't prompting the user to save a download based on the filename specified on a "'Content-Disposition: attachment; filename=..." header line. I eventually determined that my Apache installation was adding an additional header: "Vary: Host", which was throwing IE - as per http://support.microsoft.com/kb/824847 I found manually setting the Vary header from within PHP as follows header('Vary: User-Agent'); allowed IE to behave as intended. Hope this saves someone else some time, - Kal ---- Server IP: 87.124.64.96 Probable Submitter: 217.155.218.78 ---- Manual Page -- http://www.php.net/manual/en/function.header.php Edit -- https://master.php.net/note/edit/76758 Del: integrated -- https://master.php.net/note/delete/76758/integrated Del: useless -- https://master.php.net/note/delete/76758/useless Del: bad code -- https://master.php.net/note/delete/76758/bad+code Del: spam -- https://master.php.net/note/delete/76758/spam Del: non-english -- https://master.php.net/note/delete/76758/non-english Del: in docs -- https://master.php.net/note/delete/76758/in+docs Del: other reasons-- https://master.php.net/note/delete/76758 Reject -- https://master.php.net/note/reject/76758 Search -- https://master.php.net/manage/user-notes.php
