Hi,
Are you using NameVirtualHost and where in your config is the snippet you included located in the global conf file (i.e before all the others ?) ?
It is not clear to me how you can use a forward proxy defined as a name based vhost in your config file ... unless it's the default one (?).
It is either not clear to me whether you did your tests in "proxy mode", i.e. defining your Apache's proxy explicitly in your browser.
Regards.
Emmanuel
