Bug #64878 [NEW]: 304 responses return Content-Type header

From: jdesrosi at gmail dot com Operating system: Fedora 18 PHP version: 5.4.15 Package: Built-in web server Bug Type: Bug Bug description:304 responses return Content-Type header Description: ------------ I have discovered that the built-in php web server sends a default Content-Type header (text/html) when responding with HTTP/1.1 304 Not Modified. This clobbers the Content-Type stored in a cache and violates RFC2616-10.3.5 (http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.3.5) "If the conditional GET used a strong cache validator (see section 13.3.3), the response SHOULD NOT include other entity-headers. Otherwise (i.e., the conditional GET used a weak validator), the response MUST NOT include other entity-headers; this prevents inconsistencies between cached entity-bodies and updated headers." I have found related tickets related the Apache. This ticket differs only in that it refers to the built-in web server. Test script: --------------- <?php header('HTTP/1.1 304 Not Modified'); Expected result: ---------------- HTTP/1.1 304 Not Modified Host: localhost:8001 Connection: close X-Powered-By: PHP/5.4.14 Actual result: -------------- HTTP/1.1 304 Not Modified Host: localhost:8001 Connection: close X-Powered-By: PHP/5.4.14 Content-type: text/html -- Edit bug report at https://bugs.php.net/bug.php?id=64878&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=64878&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=64878&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=64878&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=64878&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=64878&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=64878&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=64878&r=needscript Try newer version: https://bugs.php.net/fix.php?id=64878&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=64878&r=support Expected behavior: https://bugs.php.net/fix.php?id=64878&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=64878&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=64878&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=64878&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=64878&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=64878&r=dst IIS Stability: https://bugs.php.net/fix.php?id=64878&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=64878&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=64878&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=64878&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=64878&r=mysqlcfg
