pca itself will continue to read pca.conf, it's only pca-proxy.cgi which 
is affected. I might have confused you with the server/client terms I 
used - forget about that. If pca is run, it reads (in this order):

     dirname($0)/pca.conf
     dirname($0)/../etc/pca.conf
     /etc/pca.conf
     $HOME/.pca
     ./pca.conf

When pca-proxy.cgi runs, it reads (in this order):

     dirname($0)/../etc/pca-proxy.conf
     /etc/pca-proxy.conf
     ./pca-proxy.conf

where "dirname($0)" is the directory where pca is installed. Settings in 
a later configuration file override settings in previously reads 
configuration files.
