org.apache.commons.httpclient.params.HttpConnectionManagerParams
This class represents a collection of HTTP protocol parameters applicable to {@link org.apache.commons.httpclient.HttpConnectionManager HTTP connection managers}. Protocol parameters may be linked together to form a hierarchy. If a particular parameter value has not been explicitly defined in the collection itself, its value will be drawn from the parent collection of parameters. @author Oleg Kalnichevski @author Michael Becke @version $Revision: 1.9 $ @since 3.0
