Well, firstly, hostaway is a joke; the fact that they refuse to make an update that most hosts have in the first place just further enhances that.
Secondly, you could try adding this to your .htaccess file:
Also, the "path_info" variable won't show in phpinfo unless it's populated; so when testing just access your phpinfo file with a query, such as:
phpinfo.php/path/data.html
And if the page doesn't work it's off, if it does work and it's not populated it doens't work. If path_info shows "path/data.html" then it works fine.
