    This simple option dramatically changes the behavior of the request body and of the entire
    call.

    The `RequestBody.writeTo()` method may now retain a reference to the provided sink and
    hand it off to another thread to write to it after `writeTo` returns.

    The `EventListener` may now see requests and responses interleaved in ways not previously
    permitted. For example, a listener may receive `responseHeadersStart()` followed by

 * API</h2>

 * <p>The successor to Guava's caching API is <a

 * nearly drop-in replacement. Note that it is not available for Android or GWT/J2CL and that it may

 * The `java.net.URI` class is strict around what URLs it accepts. It rejects URLs like
 * `http://example.com/abc|def` because the `|` character is unsupported. This class is more
 * forgiving: it will automatically percent-encode the `|'` yielding `http://example.com/abc%7Cdef`.
