I don't know if URLClassLoader is used much these days for remote class 
loading but it may be that getResourceAsStream is using getResource to 
get a URL to the resource, then it opens a connection. Locating the 
resource on a HTTP server should only require a HEAD. To access the 
resources would need GET of course.
