They're also concrete: each URL identifies a specific path (like `/square/okhttp`) and query (like `?q=sharks&lang=en`). Each webserver hosts many URLs.

### [Addresses](https://square.github.io/okhttp/4.x/okhttp/okhttp3/-address/)

Addresses specify a webserver (like `github.com`) and all of the **static** configuration necessary to connect to that server: the port number, HTTPS settings, and preferred network protocols (like HTTP/2).

        File apt = getTestFile("src/site/apt/artifact-handlers.apt");

        List<String> lines = Files.readAllLines(apt.toPath());

        for (String line : lines) {
            if (line.startsWith("||")) {
                String[] cols = line.split("\\|\\|");
                String[] expected = new String[] {
                    "",
                    "type",
                    "classifier",

Then if you go to the URLs at `/openapi.json`, `/docs`, or `/redoc` you will just get a `404 Not Found` error like:
