HTTP is the way modern applications network. It’s how we exchange data & media. Doing HTTP
efficiently makes your stuff load faster and saves bandwidth.

OkHttp is an HTTP client that’s efficient by default:

 * HTTP/2 support allows all requests to the same host to share a socket.
 * Connection pooling reduces request latency (if HTTP/2 isn’t available).
 * Transparent GZIP shrinks download sizes.

OkHttpClient client = new OkHttpClient.Builder()
    .connectionSpecs(Collections.singletonList(spec))
    .build();
```

### Debugging TLS Handshake Failures

The TLS handshake requires clients and servers to share a common TLS version and cipher suite. This
depends on the JVM or Android version, OkHttp version, and web server configuration. If there is no
common cipher suite and TLS version, your call will fail like this:

```

     * {@link jcifs.smb1.smb1.SmbFile} for a detailed description and examples of
     * the smb URL syntax.
    <p>
    The second parameter specifies how the file should be shared. If
    <code>SmbFile.FILE_NO_SHARE</code> is specified the client will
    have exclusive access to the file. An additional open command
    from jCIFS or another application will fail with the "file is being

  public boolean containsAll(Collection<?> targets) {
    // TODO(jlevy): For optimal performance, use a binary search when
    // targets.size() < size() / log(size())
    // TODO(kevinb): see if we can share code with OrderedIterator after it
    // graduates from labs.
    if (targets instanceof Multiset) {
      targets = ((Multiset<?>) targets).elementSet();
    }

 * Sessions are stored in memory with automatic expiration.
 *
 * <p><b>Note:</b> Sessions are stored in a local in-memory ConcurrentHashMap.
 * In multi-instance deployments (e.g., behind a load balancer), sessions are
 * not shared between instances. Use sticky sessions or an external session
 * store if session affinity across instances is required.</p>

files.  The first two, 6g.go and 6c.c, are a Go source file for 6g and
a C source file for 6c; both compile as part of the named package
(gmp, in this example).  The third, gcc.c, is a C source file for gcc;
it compiles into a shared object (.so) that is dynamically linked into
any 6.out that imports the first two files.

The stanza

	// #include <gmp.h>
	import "C"

is a signal to cgo.  The doc comment on the import of "C" provides
