TCP_MISS/500

What's going on?

Without Proxy the Webapplication has no Problem.
Wenn I connect via Squid sometimes it works. When I
post a big file (20k) Squid seams to connect to the DEFAULT_PARENT. Why?

Here is a part of the logfile:
------------
962612405.464 110 10.17.1.55 TCP_MISS/500 0 POST http://scaniaproxy/scania/ausgabe.php3 - DEFAULT_PARENT/www-proxy.Austria.EU.net -
962612491.127 77400 10.17.1.55 TCP_MISS/200 8236 POST http://scaniaproxy/scania/ausgabe.php3 - DIRECT/scaniaproxy text/html

The interesting Parts of my config file:
