htacces dynamically created pages

[eluser]the_unforgiven[/eluser]
Hi,

I have a codeigniter application and htaccess but when i nav to the site www.domain.com is shows things i have set that shouldn't show when going to the dynamically created home at the url of:

www.domain.com/pages/home
which is what i want to set has the main page when navigating to
www.domain.com

i have tried the DirectoryIndex with the htaccess file but because this is dynamically created how would one do this.
