[ubuntu] Jenkins behind apache but sill serving pages

view story

http://ubuntuforums.org – Hi, I've installed apache2 in my laptop, and have a couple of test pages showing properly. After installing jenkins and being able to access it locally I wanted to access it via http. I could achieve that following this http://yakiloo.com/setup-apache-and-jenkins/ But, as far as I understand, now every request to my port 80 is followed to 8080 port and so trying to access my default page I access Jenkins (and can't see the other pages). Is it possible to have both behaviours at the same time in the same computer? I've tried some solutions but not even sure about that point Thanks (Hardware)
