Package org.apache.jmeter.protocol.http.control

Class DNSCacheManager

  • All Implemented Interfaces:
    java.io.Serializable , java.lang.Cloneable , org.apache.http.conn.DnsResolver , org.apache.jmeter.config.ConfigElement , org.apache.jmeter.gui.Searchable , org.apache.jmeter.testelement.TestElement , org.apache.jmeter.testelement.TestIterationListener 
    
public class DNSCacheManager
extends ConfigTestElement implements TestIterationListener, Serializable, DnsResolver

    This config element provides ability to have flexible control over DNS caching function. Depending on option from @see org.apache.jmeter.protocol.http.gui.DNSCachePanel, either system or custom resolver can be used. Custom resolver uses dnsjava library, and gives ability to bypass both OS and JVM cache. It allows to use paradigm "1 virtual user - 1 DNS cache" in performance tests.
