note 63773 added to language.variables.predefined

WARNING!!! THE MICROSOFT INTERNET EXPLORERS 5 and 6 COMPLICATE WORKING WITH $_SERVER["HTTP_REFERER"]. (BTW, is here anyone who believes in a simple life doing it with Microsoft Internet Explorers?) In the case that your script has to check whether a requesting script is allowed to request something or not you can do it by reading $_SERVER["HTTP_REFERER"] . F.e. there is script "anna.php" requesting like so: form ... method="post" action="peter.php" input type="hidden" name="param" value="555" /form Or "anna.php" does the request like so: .. href="peter.php?param=555" ... Doing it with a normal browser it dosn't matter, peter.php can "see" in $_SERVER["HTTP_REFERER"] that the referrer-domain is correct and anna.php is the referrer. THE MICROSOFT BROWSERS 5 AND 6 WANT SOMETHING SPECIAL: Requesting by form ... will work, requesting by href="..." WON'T!! Attempting to read $_SERVER["HTTP_REFERER"] will result in "... unknown index "HTTP_REFERER" ..." - the variable will not even exist! You can imagine the consequences, right? ---- Server IP: 212.124.37.9 Probable Submitter: 80.138.80.138 ---- 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/language.variables.predefined.php Edit -- http://master.php.net/note/edit/63773 Del: integrated -- http://master.php.net/note/delete/63773/integrated Del: useless -- http://master.php.net/note/delete/63773/useless Del: bad code -- http://master.php.net/note/delete/63773/bad+code Del: spam -- http://master.php.net/note/delete/63773/spam Del: non-english -- http://master.php.net/note/delete/63773/non-english Del: in docs -- http://master.php.net/note/delete/63773/in+docs Del: other reasons-- http://master.php.net/note/delete/63773 Reject -- http://master.php.net/note/reject/63773 Search -- http://master.php.net/manage/user-notes.php
