Hi!

First, excuse my english :-P

Well, I need to customize the url depending of school's name, and i must load the information from that school. For example:

http://www.domain.com/aa_college/ -> (school's index)
http://www.domain.com/aa_college/galery -> (school's images)
http://www.domain.com/aa_college/events -> (school's events)
http://www.domain.com/aa_college/articles -> (school's articles)

Other school:

http://www.domain.com/bb_college/ -> (school's index)
http://www.domain.com/bb_college/galery -> (school's images)
http://www.domain.com/bb_college/events -> (school's events)
http://www.domain.com/bb_college/articles -> (school's articles)

And other school:

http://www.domain.com/cc_college/ -> (school's index)
http://www.domain.com/cc_college/galery -> (school's images)
http://www.domain.com/cc_college/events -> (school's events)
http://www.domain.com/cc_college/articles -> (school's articles)

I don't have idea, how i can to do it. Htacces maybe?

Thanks in advance.

Regards.
