Class NetHttpTransport

java.lang.Object

com.google.api.client.http.HttpTransport

com.google.api.client.http.javanet.NetHttpTransport

public final class NetHttpTransport
extends HttpTransport

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 URLConnection.setDefaultUseCaches(boolean).

Implementation is thread-safe. For maximum efficiency, applications should use a single globally-shared instance of the HTTP transport.
