Hi Dave, This time I gave Roller ROOT context by more conventional means - actually installed it at webapps/ROOT rather than webapps/roller. Also, following your advice, I have set "http://blog.optomus.com"; as the absolute URL inside the Admin console. Next, "/roller" was removed from mod_proxy directives for all blog domains.
Using the handle "christopher" as an example: **URL** http://blog.christopher.net.nz **roller-custom.properties** weblog.absoluteurl.christopher=http://blog.christopher.net.nz **blog.christopher.net.nz.conf** ProxyPass / ajp://127.0.0.1:8009/christopher/ ProxyPassReverse / ajp://127.0.0.1:8009/christopher/ Interestingly, browsing to http://blog.optomus.com reveals a simple page containing the message "Place your content here". I notice Roller's web.xml contains no default servlet. Is this normal? Also, roller.log reveals some interesting error messages...

Hoping there are some clues here as to what is going wrong.
