#
# URL rewriting for Etomite CMS

# if Etomite is installed in a subdirectory, change the following line so the path
# to the "root" of the site can be found, appropriately as follows:
# RewriteRule ^(.*)$ /path/to/subdirectory/index.php?q=$1 [L,QSA]

RewriteRule ^(.*)$ /cms/index.php?q=$1 [L,QSA]


# The following lines address IE 6 browser caching bugs

# MODx supports friendly URLs via this .htaccess file. In order to use it, you must change the 
# file name from ht.access to .htaccess. If you don't want to use friendly URLs, you can comment 
# the three Rewrite directives out with pound signs (like the beginning of this line).
#
# Make sure RewriteBase points to the directory where you installed MODx.
# E.g., "/" if your installation is in your root web documents directory (it comes this way by 
# default) or "/MODx" if your installation is in a MODx subdirectory, per the comments below. You
# must serve web pages via Apache with mod_rewrite to be able to use this functionality.
#
# The last two blocks of rules at the bottom of this .htaccess file address anamolies with IE 
# for Windows PCs and the way in which it caches images, which causes a distracting flicker in 
# background images when links are hovered on the page.
#
# The output compression directives immediately below serve to speed up delivery of web pages, 
# and may also be optionally commented out.

RewriteRule ^(.*)$ /index.php?q=$1 [L,QSA]

# This following two sections stops screen flicker in IE on rollovers (Bad IE Win, Bad!).
# Comment these sections out if you do not need them. They can result in having to force reload
# pages when developing sites and changing images frequently to see your changes.
