Hi, I've updated apache2 and am going through the process of changing to the new configs. Is there a how-to which describes virtual hosts? This is what I have now, but apache2 won't start and I get the error below ServerName xxx DocumentRoot "/opt/tomcat5/webapps/xx" JkUriSet worker ajp13:localhost:8009 DirectoryIndex index.jsp * Apache2 has detected a syntax error in your configuration files: Syntax error on line 73 of /etc/apache2/vhosts.d/vhosts.conf: Invalid command 'JkUriSet', perhaps mis-spelled or defined by a module not included in the server configuration Regards, Rupert Young
