### [URLs](https://square.github.io/okhttp/4.x/okhttp/okhttp3/-http-url/)

URLs (like `https://github.com/square/okhttp`) are fundamental to HTTP and the Internet. In addition to being a universal, decentralized naming scheme for everything on the web, they also specify how to access web resources.

URLs are abstract:

 *
 * <h3>Projects</h3>
 *
 * <p>{@link org.apache.maven.api.Project} instances are loaded by Maven from the local
 * file system (those projects are usually about to be built) or from the local repository
 * (they are usually downloaded during dependency collection). Those projects are loaded
 * from a Project Object Model (POM).</p>
 *

 * The performance of these calls on the underlying network. If the network’s performance isn’t sufficient, you need to either improve the network or use less of it.

 * Projects with longer downstream dependency chains are prioritized to maximize

 *
 * <p>The algorithm calculates a weight for each project as:
 * weight = 1 + max(downstream_project_weights)
 *
 * <p>Projects are then sorted by weight in descending order, ensuring that
 * projects with longer dependency chains are built first. When projects have
 * the same weight, they are ordered by project ID for deterministic results.
