Bug #64878 [Opn->Ana]: 304 responses return Content-Type header

Edit report at https://bugs.php.net/bug.php?id=64878&edit=1 ID: 64878 Updated by: cmb@php.net Reported by: jdesrosi at gmail dot com Summary: 304 responses return Content-Type header -Status: Open +Status: Analyzed Type: Bug Package: Built-in web server Operating System: Fedora 18 PHP Version: 5.4.15 Block user comment: N Private report: N New Comment: According to RFC 7232 (which obsoletes RFC 2616), section 4.1, the restrictions on sending a Content-Type header with 304 responses have been slightly loosened (SHOULD NOT). So the behavior is not necessarily a bug. However, it still seems reasonable to suppress the default Content-Type header for 304 responses. I've submitted a respective PR. Previous Comments: ------------------------------------------------------------------------ [2013-05-19 19:58:34] jdesrosi at gmail dot com 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 this bug report at https://bugs.php.net/bug.php?id=64878&edit=1
