htacess

I have a site from Pressflow D6 platform that I need to verify to use Google Apps with that domain. The site verification, requires to place a generated .html file under the root folder of that domain (in my case, under ../pressflow/sites/mysite/ ) . The .htacess of Octopus however prevents me from accessing that file (page not found). I googled around but the only thing I found is non Drupal sites and static files outside the distro folders. Can anyone suggest an easy way to deal with it?
