note 52353 added to function.header

Please read caching tutorial and test scripts with: http://www.web-caching.com/cacheability.html before copying & pasting all "urban legend" caching headers. Another note: Content-Disposition is non-standard header and sending files with readfile() doesn't support resuming, caching and might be problematic with large files. In some cases it's better to use Apache mod_rewrite instead. ---- Manual Page -- http://www.php.net/manual/en/function.header.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+52353 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+52353&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+52353&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+52353&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+52353&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+52353&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+52353&report=yes Search -- http://master.php.net/manage/user-notes.php
