What is an Url in unreal?

I often see people use url in projects, but I have no idea what a url is and what it’s used for. In my humble opinion, it is a string that describes the address of something, but I am not sure. Is there a document that introduces url?

Thanks,

This says the following:

  1. Run UE4Editor.exe
  2. Load MyGame.uproject
  3. Start the map located at /Content/Maps/MyMap.umap
  4. The game mode is UMyGameInfo
  5. Launch the game using uncooked content

In a map travel in a cooked game you might see a line like this:

/Game/Maps/MyMap?listen

This is telling the game to load MyMap.umap and be a listen server. Clients would be passed the url /Game/Maps/MyMap so it simply loads them into the map. The LoadLevel method/node is simply a wrapper for this type of URL.
