Because the response does not conform to HTTP/1.0 it is rejected. Thus the 502 error. Apache will proxy HTTP/0.9 just fine. Just repeat your test with a HTTP/0.9 client and you'll see. Apache does not translate between HTTP/1.0 and HTTP/0.9. It would anyway not be easy to do this. So if you send a HTTP/1.0 request to your forward proxy it will forward a HTTP/1.0 request to the backend. Krist -- krist.vanbesien@xxxxxxxxx krist@xxxxxxxxxxxxx Bremgarten b.
