Description: ------------ Hallo, in addition to Bug #42969 I've done some more tests. Tere is really something wrong with header() together with IIS. The behaviour is different, if I use the CGI or ISAPI. First I must also say: I have no problem to set this header correct with ASP, Perl or Phyton. Regardless if I use CGI or ISAPI. Of course with CGI, the name of such a script must be prepend with "nph-". As you can see, the only way to set the correct header/code is: Having PHP as ISAPI and using header() twice. First with the status and second with the location. This is totally different to Apache, where I must use only one header() with location and status as parameter (Testscript 2). Especially with IIS/ISAPI, Testscript 2 should also work. Or remove the status parameter at all: No different behaviour on different platforms. For IIS/CGI the actual result is acceptable. For IIS/NPH-CGI: It's not working in no way at the moment! Regards, Carsten Reproduce code: --------------- Testscript 1 (test.php): ------------------------ <?php header('HTTP/1.0 303 See Other'); header('Location: http://www.example.com/'); ?> Testscript 2 (test.php): ------------------------ <?php header('Location: http://www.example.com/', true, 303); ?> Testscript 3 (nph-test.php): ---------------------------- <?php echo "HTTP/1.0 303 See Other\r\n"; echo "Location: http://www.example.com/\r\n\r\n"; ?> Expected result: ---------------- D:\PHP>pear-request -r 0 -S http://localhost/test.php GET http://localhost/test.php --> 303 See Other Actual result: -------------- Testscript 1, 2 and 3 with nph-cgi: | D:\PHP>pear-request -r 0 -S http://localhost/nph-test.php | GET http://localhost/nph-test.php --> ERROR: Malformed response Testscript 1 with ISAPI: | D:\PHP>pear-request -r 0 -S http://localhost/test.php | GET http://localhost/test.php --> 303 See Other Testscript 1 with CGI: | D:\PHP>pear-request -r 0 -S http://localhost/test.php | GET http://localhost/test.php --> 302 Object Moved Testscript 2 with ISAPI: | D:\PHP>pear-request -r 0 -S http://localhost/test.php | GET http://localhost/test.php --> 303 Undescribed Testscript 2 with CGI: | D:\PHP>pear-request -r 0 -S http://localhost/test.php | GET http://localhost/test.php --> 302 Object Moved PatchesPull RequestsHistoryAllCommentsChangesGit/SVN commits

> What are you using exactly with IIS? > PHP FastCGI binary or ISAPI module? As you can see in the examples: both. Or in other words: I can't know, if a script is used with ISAPI or CGI on a customer installation. > note: Only former is really useful/working properly) But this is only true for PHP. Why? With other scripting languages, I have no problem to set this header via ISAPI. And with PHP/ISAPI there is only one problem: I must use first a header() call to set the status, and then I can use header() with location. | header('HTTP/1.0 303 See Other'); | header('Location: http://www.example.com/'); (The first header() call is normaly only necessary, if I want change the default reason phrase) But what ever happens in the PHP core during the first header call, should also done from PHP, if I use the status parameter in header() (like it works with Apache): | header('Location: http://www.example.com/', true, 303); Regarding PHP/CGI: A CGI which want set/use it't own headers (not parsed from the server), must have a script name which starts with "nph-" (that's not only true for IIS, also for other webservers). But if the name from a PHP script is e.g. "nph-test.php", there is no correct output at all. (as before, with other scripting languages, this works without problems.) (Or all together: With other scripting languages I use the same documented command(s) to set the header on all webservers in the same way. Only with CGI I must rename the script. With PHP the same command does work different on different webserver and nph-CGI does't work at all.) Regards, Carsten> There's also this setting: > ; cgi.nph = 1 There is no difference: | D:\PHP>cat nph-test.php | <?php | header('Location: http://www.example.com/', true, 303); | ?> | | D:\PHP>pear-request -r 0 -S -o http://localhost/phpinfo.php |\ | grep -E "cgi.rfc2616_headers|cgi.nph" | cgi.nph11 | cgi.rfc2616_headers11 | | D:\PHP>pear-request -r 0 -S http://localhost/nph-test.php | GET http://localhost/nph-test.php --> ERROR: Malformed response BTW: This setting is only available with CGI, but not with ISAPI. Regards, Carsten> Where are you reporting the bug? In ISAPI or CGI? Both. With only using this code: | header('Location: http://www.example.com/', true, 303); ISAPI does not set the (default) reason phrase. CGI (NPH) does not return a complete HTTP response message. The status line is missing.
