I am having a really weird problem. If user A access some pages of a course and then in other machine user B access the same pages, this last user suddenly sees the last pages visited and belonged to user A. This situations is very critical specially when students take on-line tests. I am not sure about the reason of this problem, but the file sessions seems to be read incorrectly by not intended users. Maybe is a bug of apache, php or both, I don't know.
Please any comment or suggestion will be unvaluable.
