The most effective workaround is to just edit mod_fastcgi.c
------------------------------------
if (strcasecmp(name, "Status") == 0) {
int statusValue = strtol(value, NULL, 10);
if (hasStatus) {
/* comment out the braindead line below */
/* goto DuplicateNotAllowed; */
}
if (statusValue < 0) {
fr->parseHeader = SCAN_CGI_BAD_HEADER;
return ap_psprintf(r->pool, "invalid Status '%s'",
value);
}
hasStatus = TRUE;
r->status = statusValue;
r->status_line = ap_pstrdup(r->pool, value);
continue;
}
------------------------------------
apache doesn't care how many times you set r->status. Set it once,
twice, 500 times even -- it doesn't matter cuz r is just a struct you
fill up before calling ap_send_http_header(r)

as an effective workaround to this problem, you can use PEAR
HTTP_Header class.
hint : method sendStatusCode()

I hadn't considered that, sorry. And thank you for taking the time.

The issue is, we send a Status: 200 very early to override the 404
(from the error-handler). After that the code branches in many
different ways, and plugins and extensions sometimes make changes to
(i.e. replace) the Status-code as well. Given that in some situations
we need to use a Location-header, we now have to make sure that nobody
has ever used "Status: " before.
So, yeah we can workaround this, but the situation as it is, is
everything but intuitive. I guess we'll have to make do....

I can't find a single evidence that a "Status:" header is treated
differently than any other header in PHP versions 4.3, 4.4 and 5.1 --
and we can't do anything about Apache changing its behaviour.
Why don't you just send the appropriate status header with the header()
call?
header("Location: uri", 1, 301);

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.

It's even that way in PHP-4.
