After I am attempting to access, my ie shows the page all right, but when I attempt opera i quickly finish on the apache 2 test page... any idea how come ?

Is Apache placed on the local machine? E.g. should you open a functional browser (inside your situation, IE) and then try to access, performs this test page appear?

Sometimes the subdomains aren't setup properly, IE: can have ok but will direct to a different location

If you're worried about this you are able to contact the web site owner and also have them update their domain configurations.
