I know this is not very right place to ask this question, but I found many beginners visit this forum, and hope that this kind of discussion will help many visitors of this forum as well as me.
The question is as the subject says. Is it possible? I read someplace that IIS and Apache can run on the same PC if they use different port numbers (e.g. IIS - 80, Apache - 8080). Also I know that Apache and Tomcat may run on the same machine. But is it possible to run all three on one machine? If yes, how should I configure those web-servers / WAS?
