Thread-safe HTTP low-level transport based on the java.net package.
Users should consider modifying the keep alive property on NetHttpTransport to control
whether the socket should be returned to a pool of connected sockets. More information is
available here.
We honor the default global caching behavior. To change the default behavior use HttpURLConnection#setDefaultUseCaches(boolean).
Implementation is thread-safe. For maximum efficiency, applications should use a single
globally-shared instance of the HTTP transport.
