How to hide query variables in a URL ('?' and onwards)

I’m wondering if there’s any way to hide the query variables at the end of a URL link. What I’m talking about is in bold below:

"http://localhost/SiteRoot/controller/action?query=variable"

My first guess is the URL Manager, but I could be wrong. Would I have to modify anything in my HTTP configuration?

Thanks.
