/**
* Strategy interface for actual execution of an HTTP invoker request.
* Used by HttpInvokerClientInterceptor and its subclass
* HttpInvokerProxyFactoryBean.
*
* Two implementations are provided out of the box:
*
* - {@code SimpleHttpInvokerRequestExecutor}:
* Uses JDK facilities to execute POST requests, without support
* for HTTP authentication or advanced configuration options.
*
- {@code HttpComponentsHttpInvokerRequestExecutor}:
* Uses Apache's Commons HttpClient to execute POST requests,
* allowing to use a preconfigured HttpClient instance
* (potentially with authentication, HTTP connection pooling, etc).
