How to set up FastDL on a TF2 server
Type sv_downloadurl "https://fastdl.example.com/tf/" in the server console so players download custom maps from that web mirror.
sv_downloadurl
Sets a web address where players download custom maps and files, often called FastDL.
sv_downloadurl <url> Examples
sv_downloadurl "https://fastdl.example.com/tf/" Use a web mirror for downloads.
Arguments
urlRequired- Base URL of the download mirror.
What it does
Without it, players download missing files directly from the game server, which is slow. Point it at a web server that mirrors your tf folder structure, with maps under maps/ and optionally compressed as .bz2.
The game's own description: Location from which clients can download missing files
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 tf/cfg/server.cfg. New to this? Start a TF2 server first.
