Hi all, I've been running Zope 2.5.1 standalone on a Cobalt RaQ that runs a Red Hat variant. Apache 1.3.12 is installed, and now I'm working on getting it to front for Zope. For the virtual site my_domain, whose stuff is stored in zope_root/sites/my_site_folder, the following URL works great: http://my_ip:8080/VirtualHostBase/http/www.my_domain.com:80/sites/my_site_fo... So I'm pretty sure I've got Zope & VHM set up correctly. Moving on to httpd.conf, I'm a bit less confident. I'm happy to post the whole thing if someone wants to see it, but here's what I believe are the relevant settings (where stand-ins like my_ip match values in the above URL). ------------- LoadModule proxy_module modules/libproxy.so AddModule mod_proxy.c Port 75 Listen 80 ProxyRequests On NameVirtualHost my_ip <VirtualHost my_ip> ServerName www.my_domain.com ServerAdmin admin ProxyPass / http://localhost:8080/VirtualHostBase/http/www.my_domain.com:80/sites/my_sit... ProxyPassReverse / http://localhost:8080/VirtualHostBase/http/www.my_domain.com:80/sites/my_sit... </VirtualHost> ------------- Set up like this, I get a RaQ-specific server mis-configuration error when I try to connect to a virtual host. Even so, a virtual host set up with DocumentRoot works fine. If I comment out the ProxyRequests directive, there doesn't appear to be a config error, but also there's no proxy service. Looking through the error logs, there is one entry that looks promising: [crit] (98)Address already in use: make_sock: could not bind to port 80 Which confuses me, since Apache is correctly handling non-proxy requests on 80 when this error kicks up. It makes me wonder if something about my proxy configuration is causing Apache to trip over itself. Does this problem look familiar to anyone here and/or have I made an obvious mistake in my httpd.conf? I've searched the Apache docs and lists without seeing anything helpful... I thought people here might have more hands-on experience with ProxyPass virtual hosting issues. Thanks in advance for any assistance, Dylan
