> Create a subdirectory called "publisher". In that directory create a

> Now create two subdirectories "subdir-1" and "subdir-1". In both of these

> Restart Apache to clear any cached modules and then cycle between the URLs

> /~grahamd/publisher/subdir-1
> /~grahamd/publisher/subdir-2
> /~grahamd/publisher/subdir-1
> /~grahamd/publisher/subdir-2
