Answer 1

See the JMeter Documentation of Sampler HTTP_Request:

HTTP Request - this has an implementation drop-down box, which selects the HTTP protocol implementation to be used:

• Java - uses the HTTP implementation provided by the JVM. This has some limitations in comparison with the HttpClient implementations - see below.
• HTTPClient3.1 - uses Apache Commons HttpClient 3.1. This is no longer being developed, and support for this may be dropped in a future JMeter release.
• HTTPClient4 - uses Apache HttpComponents HttpClient 4.x.
• Blank Value - does not set implementationon HTTP Samplers, so relies on HTTP Request Defaults if present or on jmeter.httpsampler property defined in jmeter.properties
