header("Location: http://example.com", true, 301);
?>

This is why is selected "IIS related". I cannot repro this with Apache, too. But under IIS it is broken!
 [2006-12-29 18:03 UTC] tony2001@php.net
This is why I stated I was using Apache.
Please make sure IIS does not translate 301 to 302.

What are you talking about regarding "Please make sure IIS does not translate 301 to 302." ?
 [2006-12-29 18:12 UTC] tony2001@php.net
I mean that IIS might change this code for some reason.
One of the possible ways to check it out would be to install Apache with PHP CGI and verify that it works ok.
Since they share the same code, it would mean that the problem is somewhere else.
 [2006-12-29 18:36 UTC] marc dot bau at gmx dot net
Installing Apache on Windows makes no sense to me. I know it is working with Apache 2.0 and CGI on a Linux (SuSE 9.3) box.

ASP Code Example - works:

<%@ Language=VBScript %>
<%
Response.Status="301 Moved Permanently"
Response.AddHeader "Location", "http://www.example.com/"
%>

ASP Headers results:

All on the same machine this PHP 5.2 is installed, too. Now - i think - IIS is not the cause of this bug.

Please try using this CVS snapshot:

  http://snaps.php.net/php5.2-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php5.2-win32-latest.zip

Using the latests snaps I get: HTTP/1.1 301 Undescribed
from both IIS 5.1 and IIS 7.
 [2006-12-30 21:23 UTC] marc dot bau at gmx dot net
hi. i've tested this and nothing is changed. I set a 301 and get a 302.

This bug has been fixed in CVS.

Snapshots of the sources are packaged every three hours; this change
will be in the next snapshot. You can grab the snapshot at
http://snaps.php.net/.
 
Thank you for the report, and for helping us make PHP better.


 [2007-01-01 11:12 UTC] marc dot bau at gmx dot net
Thank you. I will test the latest Snapshot.

Are you able to backport this bugfix? I think this is very important and critical bug for older versions, too.
 [2007-01-01 11:28 UTC] marc dot bau at gmx dot net
i'm sorry but i must reopen the case. i tested with snapshot php5.2-win32-200701010730 and i got this:

Isn't this the CVS Version you talked about?

you need to use the 5.2 CVS snapshot
 [2007-01-01 16:22 UTC] marc dot bau at gmx dot net
But i have used the Snapshot php5.2-win32-200701010730 !?
 [2007-01-01 16:32 UTC] iliaa@php.net
Then it is probably due to IIS overwriting the Status code. 
Based on the current code in the CVS right now PHP sends the 
redirect code set by your application.
 [2007-01-01 16:50 UTC] marc dot bau at gmx dot net
But this won't help me anything if you tell me it should be fixed and it isn't. You should test this on IIS, while it is not working as expected and i cannot fix this myself. 

So - this problem is OPEN until the bug is really fixed. I don't know why your are closing it until it is working.
 [2007-01-01 16:53 UTC] iliaa@php.net
From the PHP end of things the issue is resolved, if IIS does 
not properly handle the Status header in the event of 
redirects, that's hardly a PHP problem, no?
 [2007-01-01 17:03 UTC] marc dot bau at gmx dot net
If Perl, ColdFusion and ASP Pages are correct and PHP not, what do you think is wrong?

I think PHP! Maybe there is something wrong in the way how the status is set or how the status is transfered to IIS... i don't know if there is something special in IIS, but it looks like a PHP Bug, while all other script languages are correct.
 [2007-01-11 10:02 UTC] tony2001@php.net
Edin, could you plz verify if this problem is still valid?
 [2007-02-18 12:05 UTC] marc dot bau at gmx dot net
Additional to this a header('HTTP/1.0 404 Not Found') produces a "404 OK".
 [2007-02-19 23:23 UTC] edink@php.net
Seems that there is no way a CGI script can convince IIS to output something else than 302 response if you have location header.

Same IIS using Microsofts latest FCGI isapi has no problems with PHP outputing correct status code.

I recommend that you switch to that instead of using raw cgi, the perfomance icrease is dramatic as well.

 [2007-02-23 13:28 UTC] marc dot bau at gmx dot net
i wonder why there shouldn't be a way to handle this. 

As one example ActiveState (www.activestate.com) Perl have a CGI version and this works well, too. You should spend some time on the Perl Code, maybe there is a small trick inside.
 [2007-02-23 13:41 UTC] marc dot bau at gmx dot net
Have a look to this headers. "Undescribed" is are wrong, too. I tryed to use "php5isapi.dll" for PHP extension.
