How to set up FastDL in CS:S
Type sv_downloadurl "http://fastdl.example.com/cstrike/" in the server console so players download maps and sounds from that web server.
sv_downloadurl
Sets a web address players download missing files from, known as FastDL.
sv_downloadurl "<url>" Examples
sv_downloadurl "http://fastdl.example.com/cstrike/" Serve custom content over HTTP.
Arguments
urlRequired- Base URL of the FastDL mirror.
What it does
Point it at an HTTP server that mirrors your cstrike folder layout, for example maps/ and sound/. Files can be stored compressed as .bz2 to speed up downloads. This is much faster than downloading from the game server itself.
The game's own description: Location from which clients can download missing files
Good to know
sv_allowdownloadmust be on too.
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/cfg/server.cfg. New to this? Start a CS:S server first.
