Galaxy hosting issues

I have an app up on galaxy and its a .edu so in order for me to set the @ record since for some reason having to do with the way they got the .edu I had to set the @ record to the ips for the dns given to me in galaxy. The www is set to the dns from galaxy so that part is good, however Im having some strange behavior. When I log into the app on the url without the www and the I click a link that is set to the url with www it sends me to another page where I am not logged in. Its like there are two different sites or something? When I set the @ record I set it to the 4 ips that I got doing an nslookup for the dns given by galaxy. Any ideas? Please and thanks.
