httpd cache in wsx

Hi ppl,


I have following content_137.wsx on my streaming server
<?wsx version="1.0"?>
<smil>
<media
src="httpd://backend/backend.php/content/stream/id/137/%QueryString%"/>
</smil>



Everything works ok, but after a while (which can also be days, but can
also be hours) when I try to stream, WMS suddenly decides it will not
longer request the dynamic source
src="httpd://backend/backend.php/content/stream/id/137/%QueryString%"/>
and seems like it is using some cached version of this response
I have verified this by tailing the logs of backend webserver, no
request is recorded when this happends.

The script at httpd://backend/backend.php/content/stream/id/137/ is
configured to respond with no-cache headers, here they are:

REPONSE: HTTP/1.0 200 OK
Date: Wed, 01 Aug 2007 13:24:02 GMT
Server: Apache/2.2.3 (Ubuntu) PHP/5.2.1
X-Powered-By: PHP/5.2.1
Cache-Control: no-store, no-cache, must-revalidate, post-check=0,
pre-check=0,
Pragma: no-cache,
Etag: 6ee0731be4cc838013bbcd42af96a5be
Content-Length: 207
Connection: close
Content-Type: text/html; charset=utf-8


Any ideas?
Where would I check to verify this theory?


Thanx in advance
.
