note 60348 added to function.session-start

I am having strange problems with session_start in IE. I am creating word (*.doc) documents on the fly. This documents should be accessible only to authenticated users. If I click on document generation a standard download/open dialog box appears. When trying to directly open this word document I am getting an error from MS word, that the file cannot be found. This happens only if I am using session_start. and with session_start only works if Winword is already opened. I know this must be an IE or Winword bug, but is there any workarround? The problem is I need to authenticate each time I serve a document. ---- Manual Page -- http://www.php.net/manual/en/function.session-start.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+60348 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+60348&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+60348&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+60348&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+60348&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+60348&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+60348&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+60348&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+60348&report=yes Search -- http://master.php.net/manage/user-notes.php
