      public final class HTTPSamplerProxy
      extends HTTPSamplerBase
      implements Interruptible

  Proxy class that dispatches to the appropriate HTTP sampler.

  This class is stored in the test plan, and holds all the configuration settings. The actual implementation is created at run-time, and is passed a reference to this class so it can get access to all the settings stored by HTTPSamplerProxy.

- - ### Constructor Detail

    - #### HTTPSamplerProxy

          public HTTPSamplerProxy()

    - #### HTTPSamplerProxy

          public HTTPSamplerProxy(String impl)

      Convenience method used to initialise the implementation.
      Parameters:
        `impl` - the implementation to use.

  - ### Method Detail

    - #### sample

          protected HTTPSampleResult sample(URL u,
                                            String method,
                                            boolean areFollowingRedirect,
                                            int depth)

      Samples the URL passed in and stores the result in `HTTPSampleResult`, following redirects and downloading page resources as appropriate.

      When getting a redirect target, redirects are not followed and resources are not downloaded. The caller will take care of this.

      Specified by:
        `sample` in class `HTTPSamplerBase`
      Parameters:
        `u` - URL to sample
        `method` - HTTP method: GET, POST,...
        `areFollowingRedirect` - whether we're getting a redirect target
        `depth` - Depth of this target in the frame structure. Used only to prevent infinite recursion.
      Returns:
        results of the sampling, can be null if u is in CacheManager

    - #### threadFinished

          public void threadFinished()

      Description copied from interface: `ThreadListener`
      Called for each thread after all samples have been processed.
      Specified by:
        `threadFinished` in interface `ThreadListener`
      Overrides:
        `threadFinished` in class `HTTPSamplerBase`
      See Also:
        `JMeterThread.threadFinished(org.apache.jmeter.engine.event.LoopIterationListener)`

    - #### interrupt

          public boolean interrupt()

      Description copied from interface: `Interruptible`
      Interrupt the current operation if possible.
      Specified by:
        `interrupt` in interface `Interruptible`
      Returns:
        `true` if there was an operation to interrupt.

    - #### testIterationStart

          public void testIterationStart(LoopIterationEvent event)

      Description copied from interface: `TestIterationListener`
      Each time through a Thread Group's test script, an iteration event is fired for each thread. This will be after the test elements have been cloned, so in general the instance will not be the same as the ones the start/end methods call.
      Specified by:
        `testIterationStart` in interface `TestIterationListener`
      Overrides:
        `testIterationStart` in class `HTTPSamplerBase`
      Parameters:
        `event` - the iteration event
