ID: 36705 Comment by: ali dot sencer at gmail dot com Reported By: alisencer at gmail dot com Status: Open Bug Type: Documentation problem Operating System: FreeBSD PHP Version: 5.1.2 New Comment:
We had definitive, reproducable bug-reports for our php-application, where sending HTTP/1.1 ... type status-codes was ignored. In fact, if you read the comments on this page: http://de.php.net/manual/en/function.header.php you will find several people noting that HTTP/1.x doesn't work with CGI. In fact here is something reproducable: - use this in your .htaccess: ErrorDocument 404 /test.php - then call an invalid url - the response code will be 404 (fine). Try setting the Status code with header("HTTP/1.1 200"); it won't work (it still returns a 404), but using header("Status: 200"); yields the desired result and returns a 200. So obviously saying always use HTTP/1.x and never use Status: doesn't work in reality. To let you know where we're coming from: At this point we've come full circle: 1) We used only HTTP/1.x when starting out. Then moved 2) to use both HTTP/1.x and Status: at the same time, then 3) to use HTTP/1.x and Status: depending on sapi_name, 4) and now back to only using HTTP/1.x always user-complaints would drive the changes, and each time it would fix it for some and break it for others.

Did I miss an announcement? Since when is that? Using HTTP/1.x type headers was not working on a variety of systems with (f)cgi, which is why the following snippet was introduced (which is in a lot of applications): if (substr(php_sapi_name(), 0, 3) == 'cgi') header("Status: $status"); else header("HTTP/1.1 $status"); (which was the only solution that worked on all systems - until some recent changes in newer releases.) I could have sworn this was somehwere in the documentation even. So in which versions was this changed? How can portable applications in PHP be written, if these things change silently every now and then. Why can header("Status: ") be used at all, if it's not supposed to be used? Can the behaviour at least be "fixed" in such a way, that (f)cgi won't send "Status: " twice, which results in a 500 error by the webserver. Thanks.

One should not use "Status: 123" but "HTTP/1.x 123". ------------------------------------------------------------------------ [2006-03-12 15:39:18] [EMAIL PROTECTED] Please try using this CVS snapshot: http://snaps.php.net/php5.1-latest.tar.gz For Windows: http://snaps.php.net/win32/php5.1-win32-latest.zip ------------------------------------------------------------------------ [2006-03-12 14:14:36] alisencer at gmail dot com Description: ------------ In php-fastcgi, a header("Location: ..") call always results in an additional "Status:" header. This causes the web server to throw a 500 Internal server error. Identical code works perfectly in mod_php. The problem is specific to fastcgi. It doesn't matter what Status code the first header() call sends; the "Location:" call always adds a second "Status: 302" line. The effect is, that it becomes impossible to use header("Location;..."), if at any previous point in the script a Status header has been sent. It is also contrary to what the documentation says: http://de.php.net/manual/en/function.header.php "The second special case is the "Location:" header. Not only does it send this header back to the browser, but it also returns a REDIRECT (302) status code to the browser unless some 3xx status code has already been set." (Note the last part of that paragraph) Related: This seems to be what was happening in this bug report as well: http://bugs.php.net/bug.php?id=33225 which unfortunately was closed as bogus.
