PHP Bug Type: CGI related
Bug description: header() is wrongly handled, thus causing problems for
browsers
Description:
------------
This bug was sent in before, but marked wrong "bogus"/"won't fix". (See
Bug #38369).
PHP does not correctly handle calls such as header("Status: ..."). In
CGI mode it should process such a call as a changing the HTTP response
code (consistent with its handling of, e.g., header("Location: ...")).
However, at present there is no special handling of the Status: header.
That's why sending Status: and then Location: causes a duplicate header:
the Location: header is handled as a special case and causes
sapi_update_response_code(302) to be called, whereas the Status: header
is just added to the list of headers to be sent back to the web server
(see bug #33225 incorrectly marked "bogus", I think because the reviewer
doesn't understand CGI). Note that sending two different Status: headers
explicitly with header("Status: ...") doesn't give this error, because
the default operation is to *replace* the header, not add a new one.
Since PHP should conform to the CGI-norm, this bug should be fixed.
Although the IE does not fully stick to this norm, the FF does - which
ignores duplicated headers, resulting in different behaviour of both.
Reproduce code:
---------------
<?
header("HTTP/1.1 403 Forbidden");
?>
Expected result:
----------------
An error message created by the browser
Actual result:
--------------
IE: correct 403
FF: blank page (no output)
The headers:
HTTP/1.1 200 OK
HTTP/1.1 403 Forbidden
