Class ApacheHttpTransport
Implementation is thread-safe, as long as any parameter modification to the Apache HTTP Client
is only done at initialization time. For maximum efficiency,
applications should use a single globally-shared instance of the HTTP transport.
Default settings are specified in newDefaultHttpClient()
. Use the ApacheHttpTransport(HttpClient)
constructor to override the Apache HTTP Client used. Please
read the
Apache HTTP Client connection management tutorial for more complex configuration options.
