How to Set Up FastDL on Your Unreal Server

At Game Host Bros, we offer FastDL for your Unreal server so players can download your custom maps and mods quickly. Everything is automatic and there is no extra configuration required on your end other than uploading your custom content.

How Does FastDL Work?

While everything is automatic, there are still some things you should know about our FastDL system:

• Custom files are compressed to .uz files in /fastdl/ when you start your server. Files that come with the game are skipped, since every player already has them.
• RedirectToURL in System64/UnrealLinux.ini is set to your FastDL address automatically on every start.
• Files only get served to players after everything is compressed.
• FastDL works for players on OldUnreal's 227 patch. Players on version 226 (the one Steam and GOG sell) ignore it and download from the server instead, which is slower.
• You can view all the files online by opening your FastDL address, which you can find as RedirectToURL in System64/UnrealLinux.ini.

Here is a list of folders and file types we sync:

If what you require isn't listed, please reach out to a bro, and we will add what you require.

Using a Third-Party FastDL

If you want to host the files on your own web server instead, you can do so with the Download Redirect URL setting.

To go back to the built-in FastDL, clear the Download Redirect URL field and click Save & Restart.
