flush Clear the model and sound cache.
What it does
Flushes the engine cache so models and sounds are loaded again when next needed. It is a developer tool and not something you need on a running server.
Run it on your server
On a SLASHPLAY server, type it in the Console tab of the server page; the reply shows right under it. A value set there lasts until the server restarts. To keep it, add the line to cstrike/server.cfg. New to this? Start a CS 1.6 server first.
