Re: [Jetty-support] Jetty and mod_proxy

[Jan B. <ja...@we...>]

Hi Paul,

The thing to do when using mod_proxy is to tell it not
to mess around with the Host: header and preserve the
original. Jetty always obeys the Host: header and thus
will redirect to the apache front end.

The setting you want is called ProxyPreserveHostDirective
explained here:

http://httpd.apache.org/docs/2.0/mod/mod_proxy.html

cheers
Jan
