Apache2 reverse proxies implementation
Hi all,
I hope someone here could shine a light on an issue that I am having with apache2.
I have 2 servers with apache2 on each, which are on the same network with one router.
I have implemented what I have seen on guides on the net on the landing server such as 'Apache2 reverse proxies' which is on the ubuntuguide site (cant post the url, have not reached 5 posts yet).
It works to a point as when I enter in the url of the server which is the backend server to be served, the url changes to 'https://mail.example.com/wordpress/' and not to the landing server as before, though the result is not the address expected and which I entered from the guide above.
I suspect that there was some mail program installed which is having a conflict, I had zimbra installed at one stage.
I would really appreciate if someone here who has a simliar setup would be so kind to offer some guidance, and finally, this is a great site.
Thanking you in advance,
Regards
James

COURIERLDAPALIASD(8) Double Precision, Inc. COURIERLDAPALIASD(8)
NAME
courierldapaliasd - LDAP-based mail aliasing
SYNOPSIS
courierldapaliasd {start}
courierldapaliasd {stop}
courierldapaliasd {restart}
courierldapaliasd {query} {source} {address}
DESCRIPTION
courierldapaliasd supports mail address aliasing, as implemented by makealiases(8)[1] but using an LDAP directory instead of a GDBM or a DB
database. The term "aliasing" refers to substituting one or more addresses for another address. A one-to-one substitution results in the
Courier mail server accepting mail for one address, and delivering the mail to another address. A one-to-many substitution results in the
Courier mail server accepting mail for one address, and delivering a separate copy of the message to every address defined by the alias.
makealiases(8)[1] uses a GDBM or a DB database to perform the aliasing function. courierldapaliasd uses an LDAP directory instead.
"courierldapaliasd start" runs the courierldapaliasd process in the background, and should be executed at system startup.
"courierldapaliasd stop" stops the background process. "courierldapaliasd restart" restarts the process, and rereads the ldapaliasrc
configuration file to pick up any changes. courierldapaliasd restart must be executed in order for any changes to ldapaliasrc to take
place.
courierldapaliasd runs in the background and opens a persistent connection to the LDAP directory, and checks every recipient address using
the persistent connection. courierldapaliasd automatically starts an adjustable number of multiple processes. With persistent connections
being used, this allows alias checking to be as efficient and quick as possible.
"courierldapaliasd query source address" is a diagnostic tool. It requires that courierldapaliasd must already be running in the
background; it sends a query for address to the background process, and prints the result. Like makealiases(8)[1], it is possible to create
aliases that are accessible only to certain sources of mail, like "esmtp" or "local". The "source" argument specifies the source of the
address, such as "local", "esmtp", or "uucp".
CONFIGURATION
courierldapaliasd requires OpenLDAP client libraries, and is installed automatically if OpenLDAP client libraries are available at
installation time. The default ldapaliasrc configuration file contains additional instructions for configuring LDAP-based aliasing.
FILES
/usr/sbin/courierldapaliasd
/etc/courier/ldapaliasrc
