Is it possible to create a caching script that can cache pages that are dynamicly created?

For eg, If each page in a certain section is created by a variable in the url: mysite.com/games?=game_id

Where game_id tells the script what to fetch from the DB for that page.

I don't nesc need to know how to do it, just if it is possible and on what scale of the difficulty meter it would sit on.

I need to factor it into what platform I am going to use for my next site.

(I guess it must be possible as vB can cache posts/threads?)

Cheers,
