#42779 [NEW]: Non-standards-compliant change in 'Connection' HTTP response header

From: aya at eh dot org Operating system: Linux PHP version: 5.2.4 PHP Bug Type: Output Control Bug description: Non-standards-compliant change in 'Connection' HTTP response header Description: ------------ There seems to have been a change in the 'Connection' output header for HTTP/1.0 requests somewhere between PHP v5.2.0 and PHP v5.2.3. IIRC, according to the relevant RFCs, When processing an HTTP/1.0 request, the server should respond with an HTTP/1.1 response line if it supports HTTP/1.1, but the entity headers should be compatible with HTTP/1.0. A simple "GET / HTTP/1.0" to a PHP page in v5.2.0 returns... HTTP/1.1 200 OK Connection: close ...other stuff... ...and then closes the connections as soon as the entity has been sent. However, the same request in v5.2.3 returns... HTTP/1.1 200 OK ...other stuff... ...and then waits for another request, without sending a "Connection: keep-alive" header. This is the correct behaviour for an HTTP/1.1 request, but not an HTTP/1.0 request. In practise, this change prevents apachebench from working correctly against PHP scripts. -- Edit bug report at http://bugs.php.net/?id=42779&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=42779&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=42779&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=42779&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=42779&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=42779&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=42779&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=42779&r=needscript Try newer version: http://bugs.php.net/fix.php?id=42779&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=42779&r=support Expected behavior: http://bugs.php.net/fix.php?id=42779&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=42779&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=42779&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=42779&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=42779&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=42779&r=dst IIS Stability: http://bugs.php.net/fix.php?id=42779&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=42779&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=42779&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=42779&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=42779&r=mysqlcfg
