eZHTTPTool::hasVariable("xx") is empty in cgi mod when using
VirtualHost and Host access mode
www.mydomain/path/to?query=value
the query isn't filled not in $_GET and not in $_SERVER[QUERY_STRING] so eZHTTPTool::variable("xx") is empty.

would be helpfully to resolve $_SERVER[REQUEST_URI] for case isCGI & isVirtualHost and isHostAccessMode to fill the queries into $_GET by getting instance of eZHTTPTool

is some scripts here (9 in kernel + extensions) witch are using $http->variable("xx") on eZHTTPTool instance but they are not working for this queries .

I'm a newbie here in ezPublish an so I'm a bit to shy to write a patch for this problem - sorry

thanx for help
