For a CS 1.6 Server:
- Create a cstrike directory in your public_html folder, with folders for each filetype you wish to mirror (e.g. maps, sounds, sprites).
- Upload the files you wish to use for fast downloads to the cstrike directory and maintain the same file directory structure.
- Add the following code to your server.cfg file with your domain in the first line:
sv_downloadurl "http://www.domain.com/cstrike"
sv_allowdownload 1
sv_allowupload 1
