#33057 [NEW]: PHP returns Content-Type header for 304 responses

From: cboitel at lfdj dot com Operating system: Solaris/Linux PHP version: 4.3.11 PHP Bug Type: Apache related Bug description: PHP returns Content-Type header for 304 responses Description: ------------ When setting response code to 304 from within PHP code, a "Content-Type:" header is always added when PHP is compiled within Apache 1.3x whereas it is not for Apache 2.x This makes Apache 1.3x/PHP non compliant with RFC HTTP/1.1 for 304 responses in the case where a weak validator is used (Content-Type MUST not be returned). Reproduce code: --------------- mytest1.php <? header( "HTTP/1.1 304 Not Modified" ); ?> Expected result: ---------------- telnet localhost 80 GET /mytest1.php HTTP/1.0 HTTP/1.1 304 Not Modified Date: Wed, 18 May 2005 14:10:06 GMT Server: Apache Connection: close Actual result: -------------- telnet localhost 80 GET /mytest1.php HTTP/1.0 HTTP/1.1 304 Not Modified Date: Wed, 18 May 2005 14:10:06 GMT Server: Apache Content-Type: text/html Connection: close -- Edit bug report at http://bugs.php.net/?id=33057&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=33057&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=33057&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=33057&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=33057&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=33057&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=33057&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=33057&r=needscript Try newer version: http://bugs.php.net/fix.php?id=33057&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=33057&r=support Expected behavior: http://bugs.php.net/fix.php?id=33057&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=33057&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=33057&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=33057&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=33057&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=33057&r=dst IIS Stability: http://bugs.php.net/fix.php?id=33057&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=33057&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=33057&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=33057&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=33057&r=mysqlcfg
