I have just been in touch with my rack provider, and they enabled mod_rewrite.   I still see the following in audit, but i also had two spaces between the regex and storage in my htaccess file, so that has been corrected.  

for the first time finally a user can log in without having to click the three horizonal bars, and then home..  the site finally redirects the user into my una site.  which.. has been a great problem for most users who don't understand why they still see the splash when they've already logged in.     

So, I feel it is working now, but on an important point to mention the following:

Web-server: Apache

• rewrite_module - UNDEFINED (try to check manually: apachectl -M 2>&1 | grep rewrite_module)

is how i see in server audit.  however it is there as rewrite.  perhaps a line or two in the wiki documentation can be added to assist people in verifying the module manually, in cases where theirs is not named rewrite_module, and they uses apache2...     ie: apache2ctl -M 2>&1 | grep rewrite
