Some very similar tags:
I am going to agree with Stephen when he posted his answer, at first.
mod-rewrite (Mod_Rewrite?) is apart of the rewriting tag, but it also an actual name for an Apache Module. So are we referring to the Apache Module or not? This is the question for this.
Then URL-Rewrite is of making URLs fancier or changing them in general. So, I would keep it myself, and just remove the rewrite tag in general?
