        The problem with HTML is that it really doesn't have a concept of "state." You might be able to keep track of what your user is doing through the use of cookies but if the user has turned off cookies, then your in a world of hurt. It's pretty simple if the user clicks the likes you provide, but what happens if they simply click the "back" button to take them to a previous screen instead of hitting one of your carefully crafted links?

        There are different webservers out there, each with different capabilities. Using IIS and ASP pages on a Microsoft platform is one way

to do things...it allows you to keep track of the users state.  Overhead
can be a problem though depending on how you craft your pages.  Different
options are available depending on what web server your using.

        What your talking about is pretty standard stuff. It's just picking the right tool which will determine if your job is easy or difficult.
