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? -- Regards, Oliver
