java.lang.Object

org.archive.wayback.resourceindex.ziplines.Http11BlockLoader

All Implemented Interfaces:

BlockLoader

Direct Known Subclasses:

RemoteHttp11BlockLoader

public class Http11BlockLoader
extends Object
implements BlockLoader

Class which wraps most of the complexity of an apache commons httpclient MultiThreaderHttpConnectionManager, exposing common configuration elements to Spring configuration. This class is a near direct copy of RemoteLiveWebCache: refactoring needed.
