This class represents a collection of HTTP protocol parameters applicable to {@link org.apache.commons.httpclient.HttpClient instances of HttpClient}. 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.
