Subject: [Zope] Logging client IPs to Z2.log


Hi there,

First up:
Python 2.4.2
Zope 2.9.4

I'm a relative Zope newbie so please forgive my ignorance but I have not been able to find an answer anywhere else. AFAIK there are a couple of options for
running Zope behind Apache - PCGI/FCGI or mod_proxy. It seems PCGI/FCGI is
deprecated in later versions and mod_proxy is recommended.

However, when running Zope behind mod_proxy all of the requests to Zope
naturally come from the webserver (in this case running on the same machine)
hence all entries in Z2.log are prefixed by a client address of 127.0.0.1.

I have the following options turned on:
trusted-proxy 127.0.0.1  (in zope/etc/zope.conf)

ProxyPass / http://127.0.0.1:8080/
ProxyPassReverse / http://127.0.0.1:8080/
ProxyPreserveHost On
ProxyVia On
(in the vhost config in apache)

The trusted-proxy parameter seems to related to the X-Forwarded-For header which doesn't appear to be dealt with by Apache. It would seem that neither Apache nor Zope can communicate the client's IP by the methods I have used, as Z2.log still
contains 127.0.0.1 for every request.

So... is it at all possible to log the real client IPs in Z2.log using
mod_proxy? If not what is going to happen when (and if) PCGI/FCGI support is
removed?

It may be that you need to reconfigure apache, have a look at the apache docs:

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