As I'm new to managing Apache, I found this article, from which I want to learn how to enable mod_deflate on Apache. I use Apache 2.4 and given I'm no Apache expert, I can't strictly determine if this article talks about version 2.2 or 2.4...
How will you determine this? I am sure there is more than 1 way, but what is the most efficient/fastest way that will always work when asking if a doc deals with 2.2 or 2.4?
